HT3476 Fusion drive versus ssd drive issues

HHow can I compare the fusion drive to the ssd drive in the MAC mini

A fusion drive will be a little faster than a HDD and a SSD will be a lot faster than both, especially if it's connected via PCExpress 2.
I agree with the second half of your statement but my experience with the fusion drive VS a standard 5400 RPM HHD is that it is significantly faster, not a little. Apple has managed to find a good balance between permanently storing often used items on the SSD and using it for buffering.

T450S: After upgrading main drive to SSD drive, do not see the second pre-installed SSD drive

Hello gurus, I replaced the HD with Samsung 500GB SSD, and have been loving it. However, ever since I did that, I do not see the 2nd pre-installed 15GB SANDISK SSD Drive anymore in the explorer. Anyone know what I can do to make the second drive be recognizable by the computer? This is potentially a related problem but I also have trouble installing Windows 10, because it says it can't find a partition. Can I use the second SSD drive as the partition for the install?

This smaller SSD is designed to use software and be a cache drive. It wouldn't show in File Explorer. You can check Device Manager.

I am looking to add a hybrid drive or SSD drive to my Imac 27" 2010. What can you recommend?

I have a 2.8 Ghz i5 with 8 GB Ram and 1 TB HDD and was a bit disappointed about the speed. My 2007 24" 2.8 c2d iMac starts up faster than this new used 2010 i5. In order to make start up time faster and also start apps faster I thought of adding a hybrid drive. The Apple shop in town can install it for me, but I would need to know what would be a good option.
Any advice is appreciated.

Some option here, adding an SSD should make it a Hybrid drive in 10.8.2...

Why is my iMac Start up SSD Drive filling up without any use?

I noticed yesterday that my main boot drive, my SSD drive, on my iMac was seriously depleting in memory without me doing anything or downloading anything either so much so that but 10pm last night it was saying my start up drive was full. I ran Disk Utility on the drive and it said I had a problem and should run in Recovery HD so rebooted the computer and ran it, it said it had fixed permissions so thought all was okay but after rebooting again the memory is still running down!
I also tried erasing the disk and using Time Machine as a back up from a previous time, this had no effect. I thought it could be a Snow Leopard update that came in yesterday but that doesn't seem to be the problem as I have used a back up from before I updated...
I'm literally watching the 'Used' numbers from the Get Info on my SSD drive go up infront of my eyes every few seconds.
Any help would be much appriciated!

In your Mountain Lion's Time Machine settings, you are now allowed to designate not just one only, but multiple Time Machine backup drives, though you don't have to. I'm wondering if possibly your TM settings are backing up one of your internal hard drives both to your external hard drive AND to the internal SSD drive. You might want to check to see if that is the case, and if so, change it.
Hope this helps

How to set up new SSD drives

I just ordered an SSD drive that looks to be very fast. It is called Revodrive X2. I also just got an SSD drive a month ago. It is a Crucial C300.
I have read the article on how to set up drives, but my setup is a bit different and I would like to know where to put things based on two of the drives being very fast drives. I have (or will have shortly) the Revodrive (160GB) as my boot drive. The C300 (256GB) drive will be for programs and a few frequently used storage-type files.
I also have 2 WD black 1TB drives. This gives me a total of 4 drives (2 SSD drives and 2HD's). What would be the best setup for my drives?
Asus P6T M/B
12 GB of memory
GTX 470
4 Drives all attached to ICH10 motherboard connections

I guess you do not know that your Revodrive does not connect to a SATA port. It simply plugs into the PCIe bus. Many times trying to put applications on a different drive than the boot drive can be complicated.

Defragmentation on SSD drives

We just moved our Sybase ASE15.7 databases from standard "mechanical" HDD drives to SSD drives (IBM SAN).
We suspect that with SSD drives, ASE indexes/tables will require less maintenance against fragmentation.
1) Is reorg/recreate maintenance on tables/indexes still relevant with data on SSD drives?
After moving the db devices to SSD drives, I still see index fragmentation using derived_stat() on sysobjets/sysindexes values.
So I suspect that reorg/recreate indexes are still important but their impact on SSD won't be as important as on standard HDD.
2) Is the concept of fragmentation applicable when a table/index is sent to cache?
In other terms, once the object is loaded in cache, should we ignore the fact that the table was initially fragmented?
Thanks,
Vincent

Regardless of drive storage technology, ASE uses cluster ratio's and the like (among many other factors) to choose optimal query plans. So these number very much matter. If comparing the same query plans from mechanical drive to SSD, you obviously will see a performance improvement because the physical io's are faster with SSD (perhaps).   What you _might_ consider is changing the ratio of the two configuration parameters
        cost of a logical io = 2,        cost of a physical io = 25
which by default states that a physio is 12.5 times longer than a cache hit. For SSD, that ratio might look something more like
         cost of a logical io = 2,        cost of a physical io = 8
maybe more maybe less, your mileage may vary, but what that does is close the gap between these two costs so that the performance aspect of the storage is more likely taken into account by the optimizer. BTW - this could be true for SAN based storage (for one example) with heavy caches in front of them as well.
Bottom line is that your "fragmentation" numbers play a role in optimization and query plan determinations. Performance of the arrived at query plan is influenced by the storage tech (and cpu, network, etc).

Is anything written permanently to the Fusion Drive's SSD?

Is anything written permanently to the Fusion Drive's SSD or is it just a very large cache for the HD component?
I'm wondering, because I'd like to know, mostly out of curiosity, if the mechanical portion of the Fusion Drive were to fail, might the computer still boot from information on the SSD?

(I back it up with Carbon Copy Cloner AND Time Machine.)
So, if either part fails, the machine is quite dead until the internal drive is replaced? I ask because these two drives are detected separately in utilities such as TechTools Pro, where their S.M.A.R.T. data can be retrieved and tested independently.
If a failure of either portion of the drive totally disables the whole drive, would this sort of double the chance of a Fusion drive's failure?

Issues with m.2 SSD drive on X250

Hello, I have a brand new Thinkpad X250 with a stock Toshiba 256GB SSD and Windows 7 Professional.Since I need more storage I have purchased an m.2 SSD drive from Adata (Premier SP600, 256GB).After installing it in the empty m.2 slot, I get all the time the blue screen of death at the end of the Windows boot, just before the logon screen. This happens also when I boot in Safe Mode.I removed the m.2 drive and everything works perfectly again. To be noted that:1 - I have the latest BIOS in my Thinkpad2 - I have made a disk test of the m.2 drive from the BIOS boot menu and the drive is recognized, no defects3 - My primary SSD disk is encrypted with PGP (not sure this matters) Any idea what may be causing this and how to solve it? Thanks, Kurt

I have found the solution: after updating to the latest Intel RST (Rapid Storage Technology) driver v.14.5.0.1081 (not yet available on the Lenovo support site where a much older driver is provided), my ADATA m.2 SSD works perfectly on my X250.

Can I upgrade my HP ENVY 14 DR DRE Laptop to a blueray and SSD drive?

HI all,
Can I upgrade my HP ENVY 14 DR DRE Laptop to a blue ray and SSD drive?
cheers

You can upgrade from HDD to SSD drive, but will not recommend it as it will void the warranty on the unit.
Pertaining to bluray drive, you might have some compatibility issues unless you find the right model.

Speed up early 2009 macbook5,2 by switching mechanical hard drive to SSD

I am running Mavericks on an early 2009 Macbook5,2 4gb RAM CPU@2ghz Intel core 2 duo. It is running at an unacceptably slow speed. Network performance is very hopeless too. I am wondering if switching mechanical hard disk to a SSD would revive this macbook enough to keep it for a few more years. Please advise if this approach has a chance to improve its performance adequately. If yes, what steps to follow to migrate software on my existing hard drive to SSD?

Your Macbook has a SATA bus.
1. This is what I recommend. Some drives which are SATA 2/3 compliant do not support SATA 1. http://www.amazon.com/Samsung-Electronics-2-5-Inch-SATA_6_0_gb-MZ-7PD512BW/dp/B0 09NB8WTI/ref=sr_1_3?ie=UTF8&qid=1405128604&sr=8-3&keywords=samsung+840+pro
I have used this in SATA 1 systems without any issues (the OCZ Vector is an example of problems with SATA 1).
2. Replacing the drive can be done using these steps - https://www.ifixit.com/Guide/MacBook+Core+2+Duo+Hard+Drive+Replacement/514
3. I suggest you use an external drive and make a Time Machine Backup of your MB, before you make any changes. If you have a Time Capsule, it can help as well (otherwise see if you can find a USB/FW external drive for backup).
4. Once you have a good backup, replace the drive using steps in 2. Take the old drive from the MB and put it in an external SATA enclosure (preferably one that has both USB and Firewire), so it becomes your external boot disk. If you do not want a SATA enclosure, you can also consider a FW only enclosure.
5. You can now boot from the external disk. Restore the TM backup in step 3 to the internal SSD. You will have to format the internal SSD (because it is usually unformatted). FW connectivity will allow you to daisy-chain the TM backup and your external boot drive. The restore also makes your internal drive bootable. All your applications/settings/accounts/passwords will also be preserved this way. You are essentially restoring everything from the old drive to the new drive.
If you need help regarding TM, let me know.

How do I copy the removed SSD drive from a water-damaged MB Pro to another Mac?

My son's MacBook Pro (early 2012) was ruined by a pint of water. The insurance company kept the laptop but returned its 256GB SSD drive. I've looked everywhere online – Apple's telephone support is as good as useless given they want a serial number and want to charge me £35 – for a caddy or SATA adaptor of some sort to copy files from the Sandisk SSD drive. I basically need something I can plug the SSD drive into that has a USB lead to plug it into another Mac so I can copy photos, word docs and MP3s. I can't believe it could be so difficult - it's just a hard drive, after all. Your help greatly appreciated.

This should do the trick, and will work with laptop and desktop drives too. And it doesn't rely on power from the USB port to make the drive work, which can sometimes be an issue.

What is the Best way to set up Photoshop on a new PC with multiple Hard drives and SSD?

Hi hope someone can help.
I am considering buying a new PC (see below). We want to run both Photoshop and Lightroom on the PC. We will also be using it as a Media centre – that’s why I have two big hard drives.
I would like to know the best way to install both Photoshop and Lightroom on the storage devices. As you can see I will have two 3TB hard drives and one 250G SSD card.
For Photoshop I have read that it can be advantages to have the program on one drive the photos on another drive and the “scratch file’ on a third drive. It was even suggested that the PCs Operating system could be on a different drive than the program. Is this correct and if
so what is best to go on the SSD card? I will be partitioning the Hard Drives and I could even partition the SSD drive if that could help. In this case what size partitions are recommended?
If you can see a component below that you think would be an issue with running Photoshop and Lightroom, could you also let me know what you would recommend?
CPU: Intel Core i7-4790 CPU. LGA1150
Motherboard: Gigabyte GA-Z97M Micro-ATX Motherboard LGA1150
RAM: TWO (2) x Kingston 8GB DDR3 1600Mhz Desktop Memory
HDD: TWO (2) x Seagate Barracuda 3TB 3.5" 7200RPM 64 MB Cache SATA 6.0Gb/s
SSD: Samsung 850 EVO 250GB Internal Solid State Drive (SSD)
Graphics card: Leadtek nVidia Quadro K2200 4GB Graphic Card
Optical drive: LG Blu-Ray Combo Drive. BH16NS40
Power supply unit: Cooler Master V750S ATX Power Supply 750W, 80Plus Gold Certified
Case: Cooler Master Centurion 6Mid Tower Case
Operating system: Microsoft Windows 8.1 Pro 64-bit
Wireless / WiFi: TP-Link TL-WDN4800 900Mbps Wireless-N Dual Band PCI-E Adapter
BTW I would have liked to email this to Adobe support but could not find an email address to send it to. I hope this way works.

That's a nice system Kevin, and it will work very nicely with Photoshop. I do take it that you have 16Gb RAM in Total?
250Gb SSD is a good size, but you can still run short, and that will affect Windows performance. When you get your system, instal WinDirStat which gives you a graphic display of everything on your drive, like below. Clicking on any of the large areas will tell you what and where they are, so you can think about moving cache folders etc. to one of the HDDs.
Leave the Pagefile.sys on the boot drive. Think about disabling Hyphenate as it takes a ton of space, and too often crashes on wake up.
My Documents
Desktop
Downloads
Look at Bridge cache
iTunes backup
Other stuff like that.
Think about another 500Gb drive just for Photoshop Scratch. Drives are cheap as chips nowadays
Do yourself a favour, and invest $100 in Shadow Protect (or similar if there is such a thing) SP saves incremental backups every 15 minutes (you can set the interval, but it has no impact on performance with a system like yours). If you have a problem you can mount the back up at any of those 15 minute points, and open files from it. You can also make a bootable DVD image of your C drive, and be back up and running five minutes after disaster strikes.

Does anybody have a functioning 17" mbp with a 6Gb/s SSD drive?

I ordered a MacBookPro 17" (June 2011) with the 7200rpm hard drive which is a slow drive, but comes at no extra cost with the machine.
The ssd's Apple ships with the mbp's are relatively slow and expensive, so I do not consider them an option. I therefore ordered an OWC Mercury Pro 6G (240GB) sata3 SSD drive and replaced the hard drive with it. Under both Snow Leopard and Lion I get beach balls almost continuously. Installing the ssd in a co-workers 15" mbp makes the drives work at over 500 mb/s, so the drive is not the problem.
I explained this to the people at AppleCare's helpdesk and they state, since I used a non Apple item, they can't help me. They tell me to go to a local reseller and have them install the ssd for me. This way the mbp is still valid for AppleCare. The local reseller won't touch my mbp since I bought it online at Apple (and not at his store), plus I did not buy the OWC drive in his store. In short, AppleCare is useless here. They claim I should've ordered one of the Apple ssd's (which are basically sata2 drives).
Since the 17" mbp supports sata3 and has the fastest processors of the mbp range (which is why I bought it in the first place) I do not understand why Apple would force me to 'downgrade' to a non current ssd. I work with large 3D drawing files as well as multilayered large photoshop files, so having a fast drive is very beneficial to my workflow. The hardware in the 13" and 15" mbp's support the functionality of a 6G ssd in practice, whereas the 17" mbp only does that on paper. Selling my 17" and swapping it for a 15" model seems the only option but I refuse to believe a company that claims to be technologically advanced can ignore having specifications that only work on paper. There is no record, comment or even gossip of Apple indicating this is a problem, let alone they are working on a fix, despite finding numerous forums online where people have the same problem I have.
So for the record, on the official Apple Support site, directed to both Apple developers and users:
Is there anybody that has a functioning 17" MBP with a 6Gb/s SSD?
If you have, please let me know the specs or your machine and drive so I can see if there is a solution to unleash the full potential of my MBP.
I believe there is no sadder sight than the sullen tread of a caged (osx) Lion. Help me free the desert's fallen king!! ;-)

Thanks wjosten for your reply. I filled out a feedback form.
To comment on AussieDJ's post: I tried the OWC shielding kit, doesn't work. The problems described with 6Gb/s ssd's were all with pre March MBP's. Mine is a June 2011 MBP so I figured the problem would've been solved in the mean time. I guessed wrong there. Since I waited for the release of OSX Lion (and the trim support functionality) I thought this would solve the spinning beach ball issue. I guessed wrong there as well. Can't return the ssd anymore (>30 days) so I glued the ssd on our offices "wall of shame". Being an architecture office we have everybody in the office put up poorly designed objects here (sort of a cool and uncool board but then labelled ***? and No way!). I should've glued y 17" MBP on this wall actually (since it's hardware does not work with the 6Gb/s ssd), but the bugger is too heavy and won't stick... ;-)
The worst part of the story is that my dad got his 6Gb/s ssd to wortk in his windows notebook...and he does not skip an opportunity to rub it in (your MBP can't do no 6G)!
Let's hope there will be an EFI update!

Macbook Pro Retina doesn't see internal SSD drive

Hi Guys,
I have a problem with my Macbook Pro Retina 13(late 2012). Yesterday I've done clean install of Yosemite. Everything worked fine, and I wanted to restore my files using Time Machine. So I restarted it (command +R), plugged in my extertal hard drive, turned on TM restore option and chose my SSD drive as a place to install. Mac asked me to enter password for the SSD (default filevault2 in yosemite), I entered the password, system accepted it and then something went wrong. System told me to restart mac and try again. I restarted it, and did like previous but this time, my mac stopped to see his internal SSD drive. System was asking where to install yosemite form Time Machine and there were no drive to choose. I turned on disc utility, and I see my SSD drive there but I can't erase it, or unlock (picture in appendage). I can only verify disc and it shows that drive is fine. I've tried to install Yosemite on my external drive and boot from there,to unlock SSD in settings(I've chose my Ex. drive as a place to install Yosemite) but it didn't work. I even tried internet recovery (command+option+R) but I didn't help, SSD drive was still useless.
I think my SSD is still locked, but I don't know how to unlock it now. I don't need to use Time Machine anymore(I have my files in other drive too). It can be clean install but please, can somebody tell me what to do? I have exams this week and really need a computer :<

Start your mac up by holding the alt key. That is boot from function.
If its empty then you might have a hard drive issue. Due to your hard drive being picked up but not the partition on the drive. This will most probably be a OS X reinstall.
Erase the drive and reinstall the OS X or run a recovery mode.
Good luck
