How to optimize my disk setup?

On my editing system I have 5 disks: 2 x 1 TB 7200rpm, 1 x 500GB 7200rpm, 2 x 256 GB SSD. How should I spread my data on to them optimizing performance? The way I currently use them is: 1 x 256 GB SSD for Windows 7 64bit, programs and system files, 2 x 1 TB 7200rpm as RAID0 for media files, 1 x 256 GB SSD for the "ongoing editing project" and all its files and 1 x 500GB 7200rpm for file storage.
I am using Premiere CS5 and After Effects CS5 on an Intel quad-core system with 8GB of RAM.
I have checked the forums but was unable to find anything for my exact setup; most of the guidelines go through the systems with only 1 SSD drive.

Projects is just that - Premiere Pro and After Effects project files. I do keep audio and still images in the same folder, as they're fairly small by comparison to video files. But video clips should go on their own dedicated drive.
Creating an export requires a write cycle, you write the new file. But you have to write it with something - the clips in your sequence. Those clips are tied to actual video and audio files on a hard drive. So when you export, you're reading the source media, and creating a new file from it. Thus, reading and writing at the same time. Ideally, you don't want to be doing that from a single drive. That's what slows things down. You want to read from one (or more) drives, and write to a different drive. This keep things moving along at a good speed. What you do with the exported file is not relevant to this situation, it's the act of creating that export I'm talking about.
The things you want to speed up are primarily enhanced with a new CPU. The hard drive config will have a much smaller effect on those things.

How do you change the default User in Windows 7 on a non-RAIDed 4 disk setup?

Hi.
I have installed Windows 7 Ultimate 64bit on Darling my new machine, which has a four-disk setup without RAID, like this:
SSD OCZ -OS, Programs (C:)
WD 2002FEAX - Media Projects (D:)
WD 1002FAEX - Pagefile, Media Cache (E:)
WD 1002FAEX - Previews, Exports (F:)
This setup, and because it’s unRAIDed (four separate disks), created the User file in the OS disk, right under the Programs (x86) folder, which at times causes files, which are not programs, to automatically be saved in the User file that's in the Programs disk, when in fact Programs disk is NOT meant for storage.
Further, I cannot save stuff in My Documents because that directory leads the files (that I am saving) to the User folder in the OS disk, forcing me to navigate out of there and into an alternative disk, which is time consuming, more so than if i had a directory leading to D disk.
So, I am wondering, can anyone help me change my directory to establish the default User folder in any folder other than C?
Or, if can someone refer me to Windows 7 tutorials, resourses, that are a tad more than Dummy level.
I have heard that changing around the directory as such can mess with the OS, and though not at Dummy level, I’m quite new to PC and profusely insecure about making changes to Darling at all.
Thanks.

Hi folks.
I would like to update you about what happened regarding my wish to move the User location to another hard disk. Heeding your warning, i did NOT attempt that, but rather, moved the location of the My Documents folder in my Library, from its default place on (SSD) disk C:/ (which is the default location because that's where i installed Windows 7,) to another disk - D:/ called "Media Projects".
Here is how my directory looked before i made the change, my three hard disks were outside the Library directory that's on my SSD (Programs disk):
(I did that by right-clicking the My Documents folder in the left column of a browser window, to access the Location tab.)
What this did is, it put driver D:/ under Documents, which is under Library, see picture, which now enables saving documents quickly, by going from my Library directly to my D drive, however it eliminated the "My Documents" folder/possibility all together from the left-column list of folders in the Windows Explorer browser pane.
I am now trying to do the same with Music, Pictures, and Videos, i.e. to move them to D drive, but am unable to do so because right-clicking those icons in the directory does not produce the Location tab in Properties panel, and nor does right-clicking inside the files themselves.
Similarly, right-clicking Downloads, which i also want to have residing in my D drive, does NOT produce a Location tab in properties pane, though it does seem possible to change the directory manually...see picture.....but am wary....
I am still monitoring my new system, and will see if and how this change effects my system's performance.
Thanks.

How to configure local disk on OVM Server as storage space to create VMs

Hello,
We have installed OVM Server 3.1.1 on a machine that has 250 GB of Hard disk space [Single disk].
While installing used an option - Remove all partitions and create a new default partition layout.
Around 4GB has been used and remaining 246 GB is left as free space.
From OVM Manager - the server is discovered but didn't discovered the physical disk [i.e. remaining 246 GB raw disk space].
Can someone help me to understand how to use local disk as storage space for creating and running VM's.
Thanks
Srinivas

You can? You've used every conceivable BIOS out there? You must really be full of yourself. There is absolutely no BIOS that I know of that gives this basic function. BIOSs do not "hard partition" anything. A "BIOS" is not made for such things. Do you even know what "BIOS" stands for?
I wonder why there is some many wanting to do this and are having problems.... I mean if it is such a straight forward thing to do..... It must be down right "intuitive".
You maybe speaking of a RAID "BIOS" but you obviously think you're not. Some motherboards have integrated RAID abilities. Intel RST comes to mind... BUT this isn't a feature of a MOTHERBOARD BIOS.
I've got some $50,000 servers that will not break a single hard drive up into multiple logical drives..... Now, I haven't worked on a "Stinkpad" for many years. Don't want to. However, I have never seen one that would do what you're saying you're doing.
You maybe trying to help.... but you're leading people down a wrong path.
Its just as easy to run virtual box and use the virtual box templates for Oracle VM. In fact, its more practical if you want to run Oracle VM on a laptop for testing purposes than blowing everything away and attempting to setup different LUNS on a single hard drive.
For your review...
http://www.oracle.com/technetwork/articles/servers-storage-admin/configure-vm-templates-1656261.html
Although it's more reliable to use a separate location (such as an NFS share) for a storage repository, you can use a local disk of your Oracle VM Server instead, thus taking advantage of the local storage option. Beware, though: Oracle VM Server 3.0 doesn't allow you to utilize the unused space on the physical disk it's installed on. For local storage, you'll need at least one more physical disk. In other words, you'll need a total of two disks at minimum on your Oracle VM Server host if you want to use local storage. In practice, though, local storage is not a primary use case. The major downside to this approach is that local storage, by definition, cannot be shared between different servers.

Disk setup help

NOTE: I've seen the Tweakers page on disk setup which was helpful but I guess a quick clarification of my setup below would be nice.
I'm currently editing on an 2011 iMac with an added internal SSD for the OS and Program and wanted to know how best to use my other drives.
WORKFLOW: I edit AVCHD footage mostly and use warp stabilizer effect a TON. Also, all my footage is 60p but edited on a 24p timeline. Oh and I don't usually render stuff. Each project (event) has about 50gb of footage and when it's done, I offload it and start a new one in the same way.
DRIVES I CURRENTLY OWN: I have essentially 4 drives.
1) Internal 128GB SSD
2) External Samsung 840 Pro SSD connected via Thunderbolt adapter
3&4) Two external 2TB HDDs in RAID0 (4TB total) connected to a La Cie Thunderbolt adapter.
Tweakers page suggests putting media cache on the SSD. Okay then. I'm all for that.
Proposed SETUP:
So should I do something like this?:
OS, Program = Internal SSD
Media, Project files, EXPORTS = 4TB RAID0 (I'm okay with the risk of exports being on the RAID0 because the files are quickly burned to disc and uploaded online)
Media Cache, Preview (again, I don't really have previews I don't think so maybe I should put exports here??) = Samsung 840 Pro SSD (128gb)
What do you think? And where should I put my auto-saves? I'd put it on the RAID0 too but then if that drive fails I'd have no back up of my project file which is what happened to me this summer with my old HDD.
Thanks!

Is one of these setups better than another and why?
For Media Cache Files & Database...
1) Have it on a separate fast SSD as suggested before.
2) Have it on the fast internal SSD since I have TONS of extra Space. This SSD gets that fastest read/write speeds.
3) Have it on the fast exteranl SSD that holds the media/project files since I have lots of extra space on there too and Premiere allows one to "save media cache files next to media files when possible" so that makes it easy to clean when I'm done with that project.
QUESTION 1: Originally I had planned on #1, but I already have drives #1 and #2 so is their any real advantage to #1 and if so, why?
QUESTION 2: And of the options #2 and #3, which one is best and why?

IPod w/Cassette Adapter-How to Optimize Sound Quality?

I have I believe a G2 iPod (15 GB), and I play it in my car using a cassette adapter. I've found that to keep the sound from degrading at above average volumes, I have to make some adjustments. One, I have to set the EQ to 'Bass Reducer'. Two, I have to make sure the volume on the iPod is at about 80%. If I go above that, the sound distorts. The lower you go below that, the more hissing you get w/ the playback. I also turn the 'Sound Check' setting on.
Any other recommendations on how to optimize the sound quality when playing it through your vehicle sound system? Also, I'm thinking about getting a G5 unit (most likely the 4 GB Nano). Anyone have any feedback on whether I can expect better sound quality, in particular in my vehicle with the setup outlined above, by upgrading to the newer unit?

Various Methods to Connect to a Car Stereo System, or Listen to Your iPod in the Vehicle
Best:
Direct connection via the dock connector or headphone jack of your iPod, to the mini-jack input (or AUX RCA input jacks) of your car stereo. Not many low/moderate-end cars have this feature yet, but it is becoming more popular. Some aftermarket auto stereo units may have this feature.
There are also some after-market, moderate to fairly expensive direct interfaces, that hook into your existing car stereo to provide a high-quality, direct connection. Most will also power/charge the iPod. Pretty slick, but can be pricey ($80-$300). If money is no object, a clean way to go. Not very portable from car to car – if at all.
http://logjamelectronics.com/ipodproducts.html
http://www.myradiostore.us/auxadapters/blitzsafe/blitzsafe-m-link-ipod-interface .html
http://www.theistore.com/ipod2car.html
http://www.mp3yourcar.com/
Better:
Connect your iPod to a cassette adaptor and play your tunes through your car's cassette player. Some new cars no longer come with a cassette player, so it may not be an option. It will provide even better audio quality if you can run the audio feed out of the dock connector (see the SendStation link below). Can be portable between cars that have a cassette player and also be used in your home cassette system. $5 to $20 for the adaptors, with large variations in quality (even with the same model).
Good:
Attach an FM transmitter to your iPod and play the tunes through an unused FM station. Convenient, but wireless FM transmitter signals are susceptible to static and outside interference, and can vary in strength and quality depending on your location. Some noticeable degradation and distortion, depending on the quality of the transmitter, the sensitivity of your ears and the airwave congestion in your area. Highly portable between cars, and may be used in a home system. FM transmitters that need to be plugged into a DC auto jack may not work in a home environment (without some sort of adaptor). You can pay from $15 to more than $80 for some of these.....but for FM quality audio, how much is too much?
Marginal:
Attach an external speaker system to the iPod and play it in the car. Workable, but not too good - unless you spring for a $300+ Bose (or similar) system. But why? Only if your vehicle has no Stereo system, perhaps.
Brave Techno-Geek:
This site gives some directions on adapting a car stereo by yourself. Risky, but it has been successfully accomplished by a forum member. Fairly inexpensive....unless you screw it up.
Whichever you choose, power the iPod through your car’s DC power -- either from a power adapter, or as part of the combined audio adaptor. Have a method to secure the iPod to the dash/console/etc. See the reviews for all the various accessories at the iLounge
You will also get better audio output if the dock connection plug is used, rather than the headphone jack. See Sendstation for a novel adaptor called a PocketDock. Others types are also available via this site.
I have read positive and negative reviews of each method, and within methods there are great variations in performance of different manufacture's systems – and peoples’ opinions of their performance. Some cassette adaptors/FM transmitters work poorly, some better.
FWIW: I have the iTrip Mini & the Newer Technology RoadTrip!+ FM transmitters, a Belkin cassette adaptor (used both with & w/out the PocketDock) and two vehicles with the BlitzSafe direct interface. Using the same song in the same car, I found that the FM transmitters worked, but not as good as the cassette adapter via the headphone jack. Using the PocketDock on the cassette adapter resulted in a significant audio quality improvement. As expected, the Blitzsafe direct connect was exceptionally better than everything else: less tinny, a more warmer/richer sound, and close to true CD quality.

How to replace a disk within a parity space

I have been searching the net for better documentation on this, but so far not a lot of information on what happens when I want to do the following (this is for home use - I am not a storage admin):
I had a JBOD array with 8 disks in it. 3x3TB and 5x2TB. I had this array thin provisioned to 45 TiB. When I hit about 13 TiB of storage, the drive stopped accepting new data and it was time to expand. This made sense to me as I had
about 19 TB or 17.3 TiB of room, minus parity, I'm about there. Perhaps I could have done more to maximize usage, but that point is moot now. What I did was buy and add a new 4TB disk to the array.
I had a Storage Pool containing all my disks, and I added this new 4TB disk to the pool. I had a Virtual Disk sitting on that pool in Single Parity mode. After adding the drive, I was unable to get the existing virtual disk to use that drive.
I imagine this was due to the number of columns previously allocated to the array. I had some ideas on how to offload the data into a new Virtual Disk with more columns, but nothing really worked, so I bought 3 more 4TB disks, reduced my data footprint
to 12TB, copied everything off, and destroyed the array.
Next I re-built my media server and put the original 8 disks in place, along with the fourth new 4TB disk, as well as a 200 GB disk, a 600 GB disk, and a 1.5 TB disk that I had laying around. I'm in day 2 of my copy operation from BackupDrive1
to the new 12 disk array. When that completes, I want to use that disk to replace the 200 GB disk I was using as a placeholder.
Everything I read on the internet has been inconclusive to me thus far. Microsoft's own documentation claims that replacing a disk is as simple as removing the old disk and adding the new one, but I don't think it is. When I tested this
using the 4TB disk and the other 3 oddballs with a smaller subset of data, it definitely wasn't as easy as that.
My intuition tells me that what I am supposed to do is power down the server and replace the disk I intend to replace, then add that disk to the now degraded storage pool. At that point I should remove the old drive from the pool and repair the virtual
disk. However, I am nervous that "removing" a drive will decrease the number of columns, and that in the end I won't be able to use the space from the 4TB drive. I've seen questions on the net on how to replace a disk and none of them
seem to specifically apply to parity spaces, most are talking about either simple spaces (not happening) and mirror spaces. I understand the difference but Microsoft's implementation of this is not as straightforward as other products I have used.
In other cases it was as simple as this: Physically replace disk, receive prompt that your old disk is missing, but you have a new disk, and would you like to rebuild the data from the old disk on the new disk? Yes? Then wait patiently while
we painfully write 4TB of 1's and 0's and you're good to go. I want this button in Storage Spaces please.

Shaon,
Thanks for your reply. However, this does not sufficiently answer my question.
The 200GB, 600 GB and 1.5 TB drives are temporary drives, since from my experience, adding drives to an array with 8 or more drives does not work. I want to replace these drives with 4TB drives, leaving the smallest drive at 2TB.
Also, I was under the assumption that parity (which I'm imagining works in storage spaces somewhat like RAID 50), claims a space for parity equal to the size of the largest drive in the bunch, not the smallest, leaving me with a total space equal to the sum
of the drives minus 4TB.
I have experimented with the suggested workflow, but through the GUI this does not work. I add the new drive, remove the missing one, and get a popup explaining that my virtual disk will be "In Repair". However, this popup vanishes before I can
click OK (almost certainly a Microsoft bug). If I click OK before I finish reading this, nothing happens. The drive doesn't repair. I need to retire the disk through PowerShell, and then use PowerShell to repair the virtual disk. This
works out OK for a while, but once I start using it, the new drive infallibly gives me an error of "Stale Metadata". I have tried this with 3 different 4TB drives, so I have doubts that this is actually a hardware issue with the drives. More than
likely, this is a false positive caused by an issue with Storage Spaces. It does give me pause on continuing to use the disk, so I end up swapping the old 200GB disk back in every time and the space works fine at that point. Right now I am attempting
to replace the 1.5 TB disk instead, to see if that does anything. After that, I plan on running the Optimize-Volume -DriveLetter D -Analyze -Verbose cmdlet to attempt to rebalance the data on the disk. Should I expect that command to do anything
useful?
Just a side comment, this product has been around for a solid 2 years now. I've found the documentation to be almost non-existent, with the exception of one TechNet page that every question seems to have a link to in the answer. This page helps
almost no-one as it lacks in examples that apply to the questions that are asked. It gives little information on parity spaces, and does not equivocally answer the one question that many parity space users have, "What is the correct workflow for growing
my pool?" I understand that in a mirrored situation, you can't grow the pool without adding a certain amount of disks, but if parity functions anything like RAID 50, this should not be a limitation. It amazes me that this is the only document Microsoft
seems to have regarding Storage Spaces, and this single document has seemingly never been updated. Take this feedback however you will, I truly hope that more discussion will reach the right people and help Microsoft fix the issues with a product that
actually has a lot of promise.

Disk setup dilemma. HELP!

Hello there,
Currently, I have 3 x 2TB HDD, 1 x 1TB HDD in my Mac Pro and here is my disk setup :
1 x 1TB 7200rpm HDD = OS and Applications
3 x 2TB HDD 7200rpm (RAID 0) = Everything else (Media, Projects, Exports, Previews, Media Cache)
From what I've heard and read, it is better to dedicated drives for certain files.
I'm planning to buy a 512gb SSD for my OS and applications (going to put this SSD in my 2nd optical drive's free bay). So I wonder which disk setup is the best for doing intensive editing in Premiere Pro and animations + effects in After Effects (currently using CS5.5 but planning to upgrade to CS6).
Here is my 2 setup that I have in mind :
Setup 1
1 x 512gb SSD = OS and Applications
3 x 2TB HDD (RAID 0) = Media, Projects, Previews, Exports
1 x 1TB HDD = Media Cache
Setup 2
1 x 1TB HDD = OS and Applications
3 x 2TB HDD (RAID 0) = Media, Projects, Previews, Exports
1 x 512gb (or 256gb) SSD = Media Cache
Setup 3
1 x 512gb SSD = OS and Applications
2 x 2TB HDD (RAID 0) = Media, Projects
1 x 2TB HDD = Previews, Exports
1 x 1TB HDD = Media Cache
Setup 4
1 x 1TB HDD = OS and Applications
2 x 2TB HDD (RAID 0) = Media, Projects
1 x 2TB HDD = Previews, Exports
1 x 512gb (or 256gb) SSD = Media Cache
Some say that I should also have a dedicated drive for exports as well. But if I use 1 drive for both exports and previews, it's still okay in terms of the read/write workflow isn't it?
So, which setup is the best for performance for editing and rendering in Premiere Pro and After Effects? Or if you have other suggestions, please do tell me as well. Please do help me because I'm starting a new project soon and need to set everything as soon as possible. Many thanks!
*NOTE : I have a 4TB external HDD for backups*

Ash

Ash,
You state neither your processor(s) type or RAM here, however it is pretty likely that with the aresanal of drives that you have you will not bee too bottlenecked in the drive area. And too, various tweaks to how you configure your drives will probably not make that measurable of a difference. Certainly putting more drive power in the areas that you want to perform best could also be considered a personal choice in a sense. If you rarely export, don't put much in that area. If you export frequently, assign more / faster drive(s) to that task.
That being said, here's how I would start out if I were mounting your drives in a PC, assuming that your big SSD has decent write performance (at least 200 MB/s):
SSD - OS, programs, media cache, media cache DB
1TB - exports
3x2TB RAID 0 - everything else
I've got to qualify too that I have no clue how Apple deals with RAM and disk caching, but Windows 7/8 does a pretty good job of using spare RAM (not tied up by programs) for disk caching so that RAID 0 arrays can multi-task pretty well on simultaneous reads and writes. And, when you are doing big reads, RAID 0 really does provide quite a bit more kick than single rotating drives, even 7200 rpm models.
Regards,
Jim

Discussion regarding hard disk setup

Hello all and a Merry Christmas. I am running the Adobe CS6 suite (Photoshop, Illustrator, Premiere, After Effects and Audition), Avid Media Composer 6 and Davinci Resolve Lite 9 on my system. I have been reading various hard disk setup including the one that Ham has posted. Uptil now I have been using just one hard disk for everything. I know that is bad. I never had the money. But now I do. Here is how I think it should be like and it is very similar to the 3 disk setup mentioned by Ham.
500GB 7200 RPM for C: (OS, Programs, Pagefiles, Misc stuff like documents, etc)
1TB 7200 RPM for D: (Media Projects and Files)
500GB 7200 RPM for E: (Exports, Previews and Cache)
I can't afford a raid drive because I'd want a Raid 5 and that is considerably out of my budget. I'll get one as soon as I can. Now I have a desktop. I was thinking of having the media drive to be external with a good enclosure with a heat sink and a fan. I have an eSata port, USB 3.0 and USB 2.0. I'll keep the other drives internally and keep the media drive external because of the heat issues. Is this the right path or should I have all the drives internally? I do have a good and an airy casing. Its the HAF 922 with liquid cooling (Corsair H60) for the CPU. Please help me out. Thanking you guys in advance.

Imagine a very popular nightclub, that opens at 10 PM and long rows of people are waiting to come in.
If that nightclub only has a single door that can be used by single person only at one time, used for both entry and exit, you can imagine the waiting for people outside can be long or people inside waiting to exit. The first thing to do is make another door, one for entry only and one for exit only. That reduces the queues. The next thing to do is create multiple doors, let's say two on the North side, one for entry and one for exit, plus two doors on the South side, again one for entry and one for exit.
I imagine you get the drift. Well, each door is like a physical SATA connection, traffic can only go in one direction at a time and the people or data on eather side of the door or SATA connection have to wait. That is a simple reason why more disks are better for the multitude of tasks that need to be performed during editing. The more doors or SATA connections, the less waiting there is and the more enjoyable it is.
The C: drive for OS & programs and pagefile is mostly used for reading and housekeeping, the staff only entrance.
Other drive(s) or doors are used for projects, media, media cache, previews and exports. The slower the drive, the narrower the door, the faster the disk, the wider the door. How to organize access to the drives depends on your editing style and material, just like the number of doors in the nightclub depend on the number of visitors and their visiting patterns.
If you do smallish projects with rather easy codecs and limited or no multicam editing, the system requirements are not very hard, but if you do large and complex projects with difficult codecs and lost of multicam editing, you need a much sturdier system. A small nightclub out in the country requires less doors than a huge nightclub in a big city that caters to movie stars, celebrities and other VIP's, especially if they use the latest and greatest in presentation technology (of course with corresponding prices).
I keep coming back to this nightclub, because I think the analogy works quite well to explain that there is not one answer that suites all needs. Basically it boils down to available budget and the circumstances you are in. Now, with a 500 GB disk available, I assume your system is not the latest. I would keep it simple, forget a SSD for the moment as a boot disk, it may be overkill in your current system, and get as many 1+ TB Seagate 7200.14 or WD Caviar Blacks as your budget allows (up to 5). When you buy a new system in the future, you can take these disks along to the new system.

Disk Setup Recommendation (1xssd,1x7200rpm,1x5400rpm)

@Hi!
Any recommendation on how I should set up my disks for Premiere?
I currently have one ssd, one 1TB 7200rpm black western digital and one 2TB 5400rpm green western digital hard drive.
I tried following this guide Generic Guideline for Disk Setup but would greatly appreciate a confirmation.
Follow up question, would adding a second 640GB 5400rpm hard drive for a total of 2 green western digital drives help anything? If not then I will just leave the 640GB disk as an external and not take it apart.
Thank you for your time.
-owbert

Don't use green drives. Get another 7200 RPM drive and use the green drive for backups only.

Disk setup for Laptop on Premiere Pro CS6

So, I have read the guidlines on disk setup but I feel that it is geared towards a desktop setup. I would like to know how do I setup a laptop that has the three (3) HDD bays. I only have two drives on it and I am looking forward to buy a new one depending on how you guys reccomend it is set up. My OS disk is 128gb Crucial M4 and the second drive is a 7200 750GB seagate momentus xt. Which will eventually become:
OS - 128gb SSD
Source - 750gb drive
Render - ?????
External - cache/export/storage
Should I go for another 7200 drive of the same kind or should I remove it and go for SSD for both source and render? Thank you very much for any help.

Good, that is a strong laptop spec.
I'd vote to go with a second matching Momentus in bay 3 for sure.
Suggest you buy it, configure it, and test it out to see if you have the drive speed with your workflow to max out your cores (monitor w/ task mgr) with just the two internal drives and nothing external. I don't have much personal experience with your particular codec (sounds like Canon DSLR?), but I suspect that you will be CPU bound more than disk I/O with this setup.
Your eSATA extrernal drive or array may only be needed for backups. If it does turn out you are want or need even more drive performance, configure the two 7200 rpm drives as a RAID 0 in the laptop and bundle with something (single 7200 or G-RAID mini) coupled externally.

How can I quit a setup during installation

How can I quit a setup during installation?
The program I am trying to quit is 'CANON_IJ'

Restart or force restart the computer, if it refuses to restart, i.e. repeat the steps already shown by Noble Seven. If it stubborn, and does not restart— well, in dispair of solutions, press power button for 6 seconds until mac shuts down. Wait one minute and press power button again, you will be able to eject the disk now.
This is not a recommended solution, try to calmly quit all activities, including by forcing mac to quit them. If you succeed in logging out, you will be able to restart it normally.

Ideal disk setup for MDFs, LDFs, TempDB, and cube files?

I'm about to build an enterprise SQL Server that will run both OLTP and our data warehouse (OLAP). What is the proper disk setup for data files, please? Is it something like:
1 for MDFs
1 for LDFs
1 for TempDB
1 for OLAP files
Or something close to that?
Thanks for any guidance.

Some specific Disk Setup Questions

Alright, I've read several articles, but I'm still slightly confused. It's not too much, but just a simple matter of what difference an HDD and an SDD would make without any form of RAID.
So, let's take the following:
C: Samsung 256GB 850 PRO Series SATA III 6Gb/s Solid State Drive
for OS and Programs
D: 3TB Barracuda SATA 6Gb/s 7200RPM 64MB Cache Desktop Drive OR Samsung 1TB 850 PRO Series SATA III 6Gb/s Solid State Drive
for Source Media and Projects
E: Samsung 128GB 850 PRO Series SATA III 6Gb/s Solid State Drive
for Pagefile and Media Cache
F: Samsung 128GB 850 PRO Series SATA III 6Gb/s Solid State Drive OR Samsung 256GB 850 PRO Series SATA III 6Gb/s Solid State Drive
for Preview and Exports.*
So, this is what I may be considering as a disk setup. I don't have too much more money to spend than possibly what I have listed above, and I'm trying to determine what would be the best for After Effects and Premiere Pro, the two programs I'd main.
*One thing to note is that I would NOT keep the exports on that disk. I would move them over to something else I already have for storage. So, it's basically a matter of how much space should I have on that drive for preview files.
So, here're my questions:
For the D: drive, what difference will the HDD I have listed make (remember, Ae and Pr would be READING from that drive) compared to the SDD? See, I would prefer more space with the HDD, and like to spend less money, but if the other drives are all SSDs, will that HDD slow it all down?
How big are preview files supposed to be? I've had bad experiences with them, due to my lack of knowledge at the moment, but I don't know; just for 1080x1920 HD video, what's a general size the preview files should be per minute? (I also use several layers, so that could affect the size as well.)
If the preview files are generally fairly small when set up correctly (as in not a 40GB file per 3 minutes of 1080by1920 HD), could the E: and F: drives be run together in a RAID0? Would that offer advantages over running them separately? Or would the difference be negligible?
If it's better to run the E: and F: drives separately, should I use the 128GB drive for Previews/Exports or the 256GB drive? I know that if I did RAID0 I'd have to use the 128GB.

Yes, it's true; I have no experience building systems at all. However, I'm still unclear, entirely, on the whole HDD vs SSD thing. Thank you for your information, but I'd still like to clarify some things.
I'm mainly trying to understand more about the performance aspect of all this.
Let's take the previously revised version and compare it to your suggested one. I'll say what I think based upon what I believe to be correct, but I'm obviously missing some information here; that's where I want somebody to correct me.
Version 1:
C: Samsung 256GB 850 PRO Series SATA III 6Gb/s Solid State Drive
for OS and Programs and possibly Pagefile
D: Samsung 1TB 850 PRO Series SATA III 6Gb/s Solid State Drive
for Source Media and Projects
E: Samsung 128GB 850 PRO Series SATA III 6Gb/s Solid State Drive
for possibly Pagefile and Media Cache
F: Samsung 256GB 850 PRO Series SATA III 6Gb/s Solid State Drive
for Preview and Exports.*
*Take note, I'm putting the exports on a separate drive I already own and deleting them from the drive I originally wrote them to.
VS:
Version 2:
C: Samsung 256GB 850 PRO Series SATA III 6Gb/s Solid State Drive
for OS and Programs and pagefile.
D: HD RAID 0 array: 6x 1TB Barracuda 64MB cache RAID 0 array (x99 boards have LOTS of SATA ports)
So, let me get this straight here. Correct me if any of the following statements are wrong. I'll also have some questions associated with them.
Version 2 will be SIGNIFICANTLY slower than Version 1. I'm assuming this because Version 2 is both an HDD and SATA instead of SSDs with SATA III. However, I'm unsure of this since RAID 0 is being used in Version 2, unlike Version 1.
Version 2 will be MUCH riskier than Version 1. I'm assuming this because it's RAID 0, and if one of those six drives fails, all the data is lost. (However, since the programs are on C:, they will stay safe, along with the operating system.)
Version 2 is ALSO riskier due to the fact that I'm using HDDs instead of SSDs. Or am I wrong, are SSDs riskier than HDDs?
Under Version 2, I'll have 1TB total to put source media, projects media cache, preview files, and exports on, while keeping the pagefile, OS, and programs on C:. (even though it's six disks)
This is what I'm understanding right now. Please correct me if I'm wrong, or point out other suggestions. One final thing, as well, that I'm also unsure of.
Now, I used to use Premiere Elements 11. When I would create preview files for, say, a 13 minute HD video, the preview files (in total) would be under 1GB or just a little more. What about Premiere Pro CC makes the file sizes so different?

How to optimize your PC for the 0404 USB and 0202 USB

This is a guide on optimizing your system for the 0404 USB and 0202 USB.
Make sure the 0404 USB is using a USB HOST that is on an IRQ alone. This means no other device in the PC can be sharing its IRQ.
If you are running a hyper-threaded CPU, by turning hyperthreading off from the bios. You can set the latency at 20ms or lower and you will usually not have any latency issues.
Change Processor Scheduling to 'Background Services' - Navigate to the Advanced page of the System applet. Click on the Performance Settings button, select its Advanced tab and click on 'Background Services' for Processor Scheduling.
Switch Off Power Schemes - In the Power Options applet, choose the 'Always On' power scheme. Change the settings for monitor and hard disk turn off and System standby to 'Never', so that your PC doesn't unexpectedly conk out during song playback
Disable System Sounds - Select the 'No Sounds' scheme on the Sounds tab of the Sounds and Audio Devices applet.
Make sure legacy USB support is disabled in your BIOS.

Hi everybody.
This message to share my experience of the 0404 USB under Windows 7.
I previously operated this sound adapter under Windows XP and it was working fine with my pipe organ simulator (Hauptwerk).
When I switched to W7 on a Dell Vostro (professionnal series), sound was muting after exactly one minute . The same with a video on Yutube.....
I did all the adjustments suggested here and there on the web (sampling rate, drivers) , I tried to operate at moonlight, I shot a chicken, etc ...
After many manipulations, I noticed that, if I was doing "something", for instance moving the sound level up and down, the sound was going on ....
The solution was in part at the beginning of the topic "how to optimize your PC for th 0404, etc ....".
The keyword is "interrruption".
As a matter of fact, the Dell laptop is strongly closed. The BIOS allows no adjustment of nothing.... No way to control interruptions allocation.
BUT!!! I noticed that the two USB 2.0 ports are located very far away from each other. I supposed there would be TWO controlling chips. And I tried the second one. AND IT WORKED!
So the E-MU guy is right, the device must get a free interruption line to operate ....!

What is the best system? We have 30 iPads.

That would be fine.
