Workflow and scratch disk setting

To improve the speed on editing and rendering, what would be the best workflow and scratch disk setting for follows?!
1) video files create by Canon 5D mark II on CF card
2) Video files create by JVC HM700 (in HD, .mov format)
Above 2 formats I usually work with FCP on follow hardware ,
iMac 3.4G i7
8G RAM
Primary drive, 256G SSD
Secondary, 1T harddrive
For each project, video material most likely around 120G.
i) What would be the best setting for the scratch disk in order to boot the speed on editing and rendering?!
II) to save up the disk space on SSD, should I set the video storage on the 1T harddrive and the video n audio rending path to the SSD?!
iii) anything setting should I care while transfer both video format to FCP for a better speed for editing n rendering?
Pls advice!

don't put ANY media on your startup drive-- that would include renders. I'm guessing this is an imac with the ssd and a 1TB? what I do is have one drive for media, one for renders and a third for exports. That lightens the load considerably on any one drive at a time and arguably gives marginally faster throughput.
1TB seems like a lot, but these days it really isn't. I've got 10tb hooked up to my machine, with 3 x 1TB ready to drop into a drive dock for archives-- and I'm always out of room.
You've got to pay attention to the codec your cameras shoot in. Dunno about the JVE, but it's likely an h.264 variant of mpeg4-- do NOT try to edit with this. convert all your footage to prores LT or prores. HQ is definitely overkill.

Need Urgent Help! RAM and Scratch Disk Problem

I was recently working on making a gigapixel panorama. I made the panorama in AutopanoGiga and rendered it as a .psb. I went to go fix some stuff on the file and the first thing I did was content aware fill. The panorama ended up being 4 gigapixels before cropping. So I wanted to try content aware fill on a small portion of the image. I am using a 12-core Mac Pro with 20GB 1333 MHz RAM. I have an SSD as my boot drive and four 2TB mechanical drives, none of which in a RAID.
When I first installed Photoshop on my Mac Pro, I went into the preferences to change the memory and scratch disk settings. The first thing I did was set Photoshop to use 12GB RAM. Then I went to the scratch disk and noticed that only my SSD was set up as a scratch disk. So I unchecked the activate box next to the SSD, activated all 4 other drives, and moved the SSD to the bottom of the list.
So I started content aware fill and saw that it would take some time. So I left and when I came back a little over an hour later, Photoshop gave me a message saying that the scratch disk was full and it couldn't complete the content aware fill. Why did this happen????? I deactivated my SSD and activated four separate 2TB drives!
I went on MacRumors Forums and asked some people, and the only advice I got was to reset my settings. I did that, redid my scratch disk settings, and it is still using my SSD as the scratch disk! Can someone please help??

CAF is processor and memory intensive... most of the flashy demos of this feature have been on much smaller images.
CAF has also been known to kick RAM errors when it simply farts and dies. Is CS5 fully patched?

Optimal Scratch Disk Setting for Notebook/Macbook Pro Users

After doing a ton of research, I came across THIS guidline for different scratch disk setups but I am still not sure what would be the best setup for me.
Here is what I am working with for my Current Projects Work Station
2011 i7 Macbook Pro with SSD as my main drive and 750GB 5400rpm HD in the optical bay.
OWC Elite Mini and Dual Mini in Raid0 for Media Storage. Both 7200rpm Drives
Currently I have my scratch disk set to the following:
SSD: Startup drive, OS, Programs, Project Files and Exports
750GB HD: Partitioned - 250GB to Backup SSD and 500GB for Photo storage and PP Scratch Disk Video, Audio and Previews
OWC Minis: Media Storage for Current Projects
My question is, what can I do to optimize my premiere pro settings?
Should I move my scratch disk to my external HD since its a faster drive?

I have a very similar setup but am using a couple pieces of new gear. Wondering if Harm or any of the rest of you have any advice.
2011 i7 Macbook Pro with 500GB SSD as my main drive and 750GB 5400rpm HD in the optical bay. The SSD is a new

I have various LaCie drives that contain projects, media, exports connected via LaCie Tbolt esata adapter. So these are drives I've had for years that are now running at 3G esata speeds.
I'm not using the 2nd internal drive for anything since it is 5400rpm. I just use it for backups, photo, music storage.
So I ususally work small projects with the projects, media, exports, renders all pointing back to the esata connected external LaCies.
Should I point media cache to the 500GB SSD my internal c drive? The answer to this is still confusing since I've read many conflicting posts in various places.
Any other suggestions for now with this setup? (External Tbolt connected raid not yet in my budget.)

Raid card and scratch disk setup for FCP

Hi Guys
Can anybody tell me what is the correct way to set up a raid card and scratch disk for FCP if you have 3 x 2TB internal hard drives, with the OS on HD1 and drives 2 and 3 dedicated for FCP
Also with this i also have all my documents i.e work stuff, invoices, pictures, music ect from my old windows PC and used to have them stored on HD2 with the Windows 7 OS on HD1 - i have been told that it is fine if i put this on the same drives as FCP is this correct...?
i only ask this as i have been told how to do it in different ways by 3 people......

Thanks John, although i'm rather embarrassed to admit that I am a complete newbie when it comes to technical/computer hardware terms (i.e. I have no idea about different types of disks, other than a HDD and a SSD, or even what the difference is between your media cache and a scratch disk).
This means that after reading all the links you so helpfully provided hasn't done much other than making me feel even more stupid!
The best that I can conclude from what I think that i've understood is that I will use:
Intel 530 Series 120GB SSD for O/S, Programs (and Pagefile?? No idea what this is, sorry)
Samsung 840BW 500GB - Scratch Disk (is this the media cache?) and preview
Seagate Barracuda 3TB HDD - media, projects, and exports
Please tell me if i've got something around the wrong way....
Thanks again.

Startup disk and scratch disk full messages

I use my mac a lot for digital photography. I use iPhoto to catalog, and PS Elements 3 to edit. I've been getting messages that my startup disk is full, and my scratch disk(s) are full; I can no longer save or print images from PSE3.
Please help me understand what these messages mean, and what steps I need to take to empty my startup disk and scratch disk.
Thanks
Greg

Greg:
As big as you can afford. There are 160 G external FW drives that are pretty reasonable. I've used the Mercury elite drives from OtherWorldComputing and have been happy. I'm sure others will pipe in with their good experiences with other brands.
Since the Mini doesn't have FW800 capability you can save a little by getting a USB2/FW400 model instead of the USB2/FW400/800 one. However, if you ever upgrade your Mac it probably will have an FW800 port. The price difference is about $25.
This link is for the Mercury Elite-AL Pro FireWire 800/400+USB2 and shows the prices for each type and size.
The The Mercury Elite Pro Classic is what I have. The price difference between the the two types is about $25.
If you can afford a larger one then do get it as you could then partition it to clone you current drive to one partition and make it a bootable partition in case of problems with your internal drive. Then use the other partition for long term storage, and day to day backups of user documents, etc. Even put you iPhoto and iTunes libraries on it.
With CompUSA going out of business in a lot of places you might find a very good deal on some external FW drives. Be sure to get one with FW so it can be bootable.
LaCie's drives are very popular also. CompUSA has a LaCie d2 Extreme Triple Interface 250GB Hard Drive for $179. If you have a store near you go into it and see what they have on the floor. Some don't have extra FW ports for daisy chaining. The OWC's do.

Setting up RAID 0 and scratch disk from blank drives?

Folks,
Howdy again from NC. I've been setting up an AMD Phenom II 955 to handle PPro CS5 as well as possible, within limits. I built four of these machines for my math class, and am going to give CS5 a go on one of them before caving in and migrating my Production Premium to an i7/X58 platform. Maybe I'll get lucky and find this computer works acceptably with PPro, especially if I transcode my T2i AVCHD footage (likely Neoscene).
I put three new disks into my build yesterday and would like some pointers on setting them up, if I may ask. I have read through a number of posts on this, but don't find direct answers, unfortunately. I've never set up a RAID and want to get it right.
I have two Caviar Black drives for my RAID and a Hitachi Deskstar for my scratch disk. The Blacks are new out of the pack and the Hitachi has had zeros written to the drive. How to begin?
Anticipated issues:
* Do I need to format the drives in a certain way? I had planned on going into Disk Management and setting up a volume on each as my first move. Right now, they aren't even recognized under My Computer. Under Disk Management, all three show as unallocated.
From memory, I right click in the unallocated space and select an option for setting up the volume. Prior to this I only used straight-up drives, no RAID, and after writing zeros to a drive selected "New Simple Volume". It seems to me this is the move to make on the single scratch disk.
But how about the two RAIDed drives? We also have options to set up as "New Striped Volume" or "New Spanned Volume". If the answer is to set as as "New Striped Volume" for the RAID 0 I have planned, do I do this before or after installing the RAID software?
* My documentation for setting up the RAID on my motherboard doesn't indicate when to change my BIOS setting for the two SATA channels from IDE to RAID. Should I do this before or after running the software to set up the RAID? Do I need to go into the software setup with the two SATA channels already configured as RAID?
Right now, all SATA channels are configured as IDE.
* After getting my disks set up, I'd like to optimize my system for editing (turning off unwanted features, etc.). I've been looking all over for a link to an outside site I had bookmarked from a prior post, but lost it on re-install. Anyone recall what the favored link was? It started as a long page of instructions in simple typeface.
In the end, my disks are as follows (unless someone makes a case to use them differently):
OS/Programs - 1TB Caviar Green. Yes, I know the deal on green drives, but I needed to use this drive somewhere. I figured using it as the OS drive would be the best spot for the slowest drive. Maybe I botched this and should have used the following drive for the OS? I had transfer rates in mind and thought the Scratch drive should be faster?
Scratch - 750GB Deskstar 7K100 series. This drive was tops 18 months back when I bought it.
RAID 0 - Two 640GB Caviar Blacks (32 meg cache, twin processors). A bit older in the Black lineup, but the drive charts show them working quickly.
To ask one dumb last question, which will really show my newbieness, I use the scratch drive for page files (right? and what else?) and the RAID for holding any media to be worked upon and for encoding the final project?
I've been reading on this forum for over a month and am amazed that as I have the drives for a RAID, I can't find good links to tell me what to do. I know I am asking redundant questions here but have already spent two hours with the search engine and am only getting tangential anwers (ha! math joke).
Sorry to be asking such newbie questions all over again, but my luck with the search engine hasn't been so good of late. Maybe Bill's idea of creating a sticky section for common questions is a good idea.

about 75-80% of the systems we ship, ship with this config (others would be bigger arrays or no array)
1)OS
2) project drive 2 x raid 0
3) render to/export drive 2 x raid 0
4) back up (pick your poison)
while i cant speak to the older WDs (we have not used them for 3-4 yrs until now)
i can tell you with Seagate and now WD we have not seen the issue that applies to this inRaid 0
we are aware of the timeout issue this happens with controller cards and seagate or WD with large raid 5/6
simple answer use enterprise drives for raid 5/6
if you look at all the external raid resellers Sonnet etc they all use enterprise drives (mostly seagate)
so do we for large raids.
(drobo does not so buyer beware (green), we like to sell drobo without drives in it and use ours)
again BACK UP do not assume your raid 3/5/6/10/1 whatever is bullet proof, trust me its not
so even if you have a loss it should be at best nominal
something i dont think i have seen mentioned enough either
the single most common cause of drive failure (or any component failure) is Dirty Power!
dirty power can be spikes but are usually brown outs (very common in large older cities) or even low voltage coming into the home/office
this is the most common.
rather than a clean 120v you could see it as low as 105v
the other is being on a circuit with a large appliance.
ever see your lilghts flicker when the AC kicks on?
buy a good inline filter UPS. add 20% MORE wattage than your power supply
dont forget to add accessories LCDs, Audio interfaces, speakers/studio monitors etc.

Hardware: SSD drives and scratch disks

Hi,
I am building a new system for Photoshop. Two quick questions:
1. I note in Adobe's system reqs it says Photoshop cannot be installed on flash-based storage devices. Does this include SSDs? Is there a genuine problem here (i.e. if my application drive is an SSD the PS won't work)?
2. I have not previously had a so-called "scratch" disk so I don't really know what it is or whether I need one, or more than one. What's the general advice here? - separate drive to the PS application drive? also separate to the Windows drive? How big? Will an SSD be a good choice for a scratch drive?
Thanks in advance,
Alastair

G'day,
In answer to your query SSDs work fine to install cs4 on bar the following I'm having.
I've built a new system using ssds.and is working fine bar one problem
Specs of the system is
I7 920 cpu, Asus P6t se mb, 12gb ram, 128gb ssd, 64gb ssd, 4gb raid 1+0 array onboard, nvidia geforcegtx260. I use the 128gb ssd as the os and programs drive. The raid is the data drive. All works brilliantly except when I set the 64gb ssd as the scratch disk the following happens
"Could not open a scratch file because the file is locked. Use the 'Properties' command in the Windows Explorer to unlock the file."
I hit OK and get this error -
"Could not initialize Photoshop because the file is locked. Use the 'Properties' command in the Windows Explorer to unlock the file."
Pressing ok then shuts the program and I need to reset cs4 prefernces and then it all works fine. OS is Win7 64 bit.
Now I have just got to try and fix this problem Anyone got suggestions?
Cheers
Onslow
Hmm, seems to have stopped doing this now after resetting the scratch to the ssd and then rebooting. All is now fine and wonderfully quick.

LR and Scratch disk

Hi All,
Hoping you can help me understand LR better.
LR must write to disk (for example the history states) and i'm just wondering where it all goes! (I'd like to be able to configure my drives / location of catalog etc without invoking irrational witch craft.)
When generating previews - it's the catalog previews.lrdata
What about
History
Cache
Calculations in Develop module
Processed files in Print module before it goes to print (not draft mode)
etc
etc
In PS you're obviously able to assign a scratch disk, in LR you're not - but i would have thought they'd both have similar needs?
How does it work - anyone got any ideas? Haven't been able to find anything.
Cheers

Hi John [edit, McW],
That would make sense (cat on boot, images on other) but it would be lovely to find out how the app actually works. I read Jeff Schewe say that he has his (PS) images and (PS) scratch disk on different partitions of the same disc (or raid 0 to be factually accurate) which seemed a bit counter intuative, but because the computer only "works" on an image once it's been brought in from the disk, it only ever reads or writes from one of the partitions at any given time.
My impression is that LR isn't very disc intensive - by looking at activity monitor. The CPU use seems to max out, and the memory can run quite high - which implies that it gets the info in, works on it and then stores it all in memory rather than disc cache. This then means that the limiters are CPU and RAM, and not disc speed. (Which ties in with there being no scratch disk.)
But as other people have wrote on these boards, LR is very slow at resolving thumbs compared to other apps, which i guess wasn't something that was hoped for by the engineers (but this could be because LR has so many (more) variables that come from the develop module). So, i guess if the limiters are CPU and RAM, then there's not much you can do to speed it up.
Perhaps the best thing to do is to quit other apps - free up as much memory as poss, that is if you don't fancy popping out to the shops to buy a new computer or some RAM. Bit of a dissapointing conclusion!
With me, LR's reasonably fast, but it is the biggest brake on the whole of my workflow (that's with auto write disabled - shame as the xmp side cars are rather robust). To print when not using draft mode is a pain - for example a 12 image contact sheet might come from around 1/4 or 1/3 of a Gb of RAW files which then have to be processed - in this case, slow shouldn't surprise anyone ... oh it depresses me just writing it!
But the app itself is such a fantastic development! The stuff you can do with it is incredible, and i really couldn't do with out it ... thought when there's a tight deadline it really does kill me!
Cheers

Performance and scratch disks

hello!
i am currently working with the follow:
Mac Pro 3.5GHz 6-Core intel Xeon E5
64GB RAM 1867 MHz DDR3
500GB flash storage
external
G RAID 8TB thunderbolt
my question is regarding my photoshop performance, recently i have been working on some massive files, like huge! 133in x 65in with many layer etc! and I feel like the performace could be a little quicker.
Can anyone recommend the ultimate in external drives to use as a scratch disk - fast access and reliable.
thanks in advance

I use Seagate and Western Digital.. I think they both have USB 3 solid state drives. You might have a look at those.

PS7 and Scratch Disk Full, using XP SP3 with 1 HD... how to fix?

I've searched the forum, yet couldn't find an answer or fix... I installed my old PS7 on my new computer running XP with SP3 on a dualcore Intel, 1.5T HD (only one drive), 3Gb of RAM-- not enough money to upgrade PS, computer took first dibs... PS7 refuses to open - after booting, comes up with a pop-up error stating the Scratch Disk is full, then shuts down.
My old system (W-2000, 20Gb single HD, with 1.8 Pentium processor, 1Gb of RAM) worked perfectly with PS7 - never had any problems...
I've tried all fixes possible... HD is not even close to fragmented as is a new drive; not enough programs installed yet, or use on machine, for disk clean-up to be necessary; forced creation of the preference file (changed name to .old); and did the ctrl-alt-shift to boot to defaults. No idea what is going on or why it would say scratch disk full.

Uaphil wrote:
Actually, there are no partitions on my drive. (I didn't realize PS needed a different drive or partition) My old computer and HD didn't have partitions either, and worked perfectly.
Could it be an issue with PS7 and the size of the HD? If so, is there a patch for this?
The point isn't that Photoshop needs different drives or partitions but that, as you suggest, the old PS 7 has problems with drives much bigger than were imagined in the days it was written.
However there are advantages in having the the scratch disk on a separate physical drive from the system drive where the paging file normally resides.

Data File And Scratch Disk

Searching the forum I have not found a very clear answer as to whether having the data file you are working on be on a separate hard drive from the scratch improves performance. I have finall found what seems to be an answer here:
http://macperformanceguide.com/OptimizingPhotoshop-Conclusions.html
To quote the important statement regarding this:
"It’s OK for the scratch volume to use the same physical hard drives as your data volume; access to the original file and scratch volume is almost always at different times, so there is little or no head contention"
Therefore it appears to me that if the physical scratch disk is divided into two partitions then one partition can be used as a scratch disk and the other to store the files being worked on. Does this make sense? I would assume that this is also true on a Windows machine or is there any reason to believe otherwise??
Howard

With still images, it will probably make less of a difference, as the image file is read from the HDD, when Opened. It is not accessed again, until you Save. Now, there will be a short period of time as the image data is read, and also probably written to the Scratch Disk, but that will be quite short.
That said, I always keep my media drive(s) separate from my Scratch Disks to allow for the best throughput. With the price of HDD's, there is almost no reason to NOT split the duties of the physical HDD's (note the word "physical," as you do not want partitions). Fry's (Western US retailer) just had a Seagate 1.5TB ATA-300 for US$89.00. Obviously, an eSATA II will cost more, but you get the idea.
I've always kept my Scratch Disks on empty HDD's, going way back. Obviously, a faster HDD for Scratch Disk would have a bit more benefit, than it will for the media drive.
Good luck,
Hunt

Final Cut Pro and Scratch Disks

Hello All,
I have been reading some books and posts on various fourms and I am a little confused about something, maybe someone can provide me some advice.
Lets say you have three drives (all non-raid). The first, a 10k RPM drive holds your MAC OS and all your applications, like Final Cut and After Effects. Your second drive a very fast (15k rpm, 75 gig) but very small drive is your "scratch disk." Your third drive a normal (7.2k RPM) 1TB drive is used to store all your media/graphic/audio files.
Tell me, would there be much performance improvement with such a configuration vs. having the scratch disk be the same drive as the one the actual application is on, with the stored file on the 1TB drive?
Thanks your time, attention and responses people.

"I was under the impression from what I've read that the scratch disk (which I understand is a drive the computer will use when it runs out of RAM to process filters etc like in Photoshop)"<<<</div>
In FCP, the scratch drive or 'capture scratch' drive should be any drive other than your system drive (with OS, apps, etc.) It has no relationship to RAM, while other apps may.
I've not worked with Vista or Bootcamp, so can't really advise on drive speed/performance. I do remember getting our first G5 with a 10K rpm/60Gb system drive and regretted not going for the 7.2K rpm/250Gb system drive for more internal storage, when I found that FCP ran fine on the 7.2rpm drives.
I keep a variety of 'media' types on my scratch disk, but try to limit it to my captured video files for organizational purposes. This makes it quicker to locate and trash the video clips when I'm done with them....NOTE: I will only trash video that has been captured with valid original source timecode....all other 'media' gets archived for future use, if needed.

What size for OS/apps SSD and scratch disk SSD ?

Hi !
I need a SSD for my OS with the full CS6 Cloud and few others apps (but no games, pictures, songs or other personnal stuff),
that's mean between 70 and 80Gb. So I think I'll need only a 128Gb for that.
I also need a scratch disk, so despite I prefer a fast and large disk like the Barracuda 3Tb, I read it will be better to take a SSD.
My workstation is a 6x core, with 64Gb RAM, and 6x HDD for projects, render and footage (4K R3D and 1080p PRORES).
My questions are :
1) OS/apps SSD :
Even if I only need 80Gb (or a few more like 90Gb max) of storage, do I need to take more than 128Gb ?
Is it possible that the OS fill my disk with lots of temporary files ?
And the same for Photoshop, Premiere, After Effects or others apps ?
I know those apps will use the scratch disk, but maybe others temporary files will be write on this OS/apps drive ?
2) scratch disk SSD :
Like I said, I prefer larger drives, but as I understood, SSD will be better for preview and temp files,
and actually I'm working with 4K R3D footages and 1080p PRORES.
So do you think 128Gb will be enough for a scratch disk, to use with CS6, Blackmagic Resolve, and others 3D apps, like Maya ?
Of course I can empty them regularly.............. but is it enough ? Or 256Gb, or higher will be better ?
Or just a fast WD Velociraptor 1Tb or even a cheaper Barracuda 3Tb hard drive will be good enough ?
Thanks guys.

Thanks for your fast reply.
But, I'm confused.... if the OS and the apps can fill my disk with lots of temp files, how a 128Gb can be enough ??
Maybe you mean that those apps will fill the SSD with "hidden" files, but not reach the limit of 128Gb ?
About Windows, I didn't knew I could make a scratch disk only for this temp files.
Do I have to put the Windows temp files in the scratch disk also ?
And you don't think a Velociraptor with 1Tb will be a good solution between the speed of a SSD and the size of a HDD ?
My drives (alone or in RAID 0) are directly connected from the motherboard P9X79 PRO, trought the X79 chipset, and the Marvell chipset.
But I read that the Marvell chipset has only 500Mb/s in total bandwitch divided between the 2 drives..... I'm not really sure....
but even if it's true, I don't think the OS/apps will take a lot of bandwitch (except when I'll start an apps),
and it will surelly let the full bandwitch for the scratch disk. Don't you think ?
4 drives are connected to the X79 chipset :
- 1x SATA 6Gb/s - Barracuda 3Tb (projects)
- 1x SATA 6Gb/s - Barracuda 3Tb (renders)
- 2x SATA 3Gb/s / RAID 0 - Barracuda 3Tb (footages)
- 2x SATA 3Gb/s / RAID 0 - Barracuda 3Tb (footages)
2 drives will be connected to the Marvell chipset :
- 1x SATA 6Gb/s - SSD (OS/apps)
- 1x SATA 6Gb/s - SSD or HDD (scratch disk for CS6 and other "video" apps)

Optimum program and scratch disk setup

Hi - I am about to upgrade to Premiere Elements 7 (from 2.0) to accomodate AVCHD from a new camcorder. I also just put together a new eSATA RAID array with 2 10k RPM disks cannablized from another machine. My question is what is the best place to load program and define scratch disks. System description is:
Vista OS on C: drive, 230GB 7200 RPM SATA, quad core processor
E: drive 7200 RPM SATA, 250 GB - this one is basically empty now
L: drive 2x 10k RPM eSATA 138GB total, in a striped RAID config
Currently I have Premiere ELements 2.0 and Photoshop CS2 on C: drive with L: = first scratch for photoshop and E: as secondary scratch drive.
I'm pretty sure I want the fast RAID drive for scratch in any case, but would it be better to load the programs onto the E: drive and use C: as secondary scratch? Or would it in fact be better to put the programs on the fastest RAID drive L: and use E: and C: as primary and secondary scratch drives?
If there's any point in defining even more scratch disks I have a 320G striped RAID made from 4 80GB 7200 RPM drives on another computer (IEEE1394 connecting that drive to the other computer), via wired ethernet, and will soon also have a NAS box on the network in a mirrored RAID for backup storage. But I'm thinking the local drives on the main computer above should be adequate for good performance editng video and photo.
thanks!

If you have not looked at the links in THIS ARTICLE, you will find a lot of useful info on the setup and utilization of your HDD's. While it's written with PrPro in mind, most applies directly to PE, as well.
Good luck,

Photoshop and Scratch Disks ?

If I have 4 Scratch disks does photoshop use all scratch simultaneously or does it wait for the first scratch to fill up before it starts to use the next one ?

It waits for the first to fill up, then uses the second, etc.
