Also, setup and configuration requirements (for example that you must re-flash the drive with the version supporting GC for use with RAID under windows 7) are not documented except in various postings on OCZ forum, and even then not in one place or in an orderly manner - if the default setup does not work with your configuration, expect to spend HOURS reading your way through LONG threads - and taking LOTS of notes - to learn all the little details you will need for success.
Eventually I did get everything working under 1.40 and TRIM, only to have the drive crash in an un-bootable state after a few hours (sigh...)
After reading extensively on the OCZ forum, and two discussions with OCZ tech support, I finally decided to download the ISO for a Windows 7/32 bit rescue disc, flashed the DRIVE to 1.41 to implement GC, ran OCZ's "sanitary erase" and wipe the drive (SE will not run if you boot from a 64 bit rescue disc), reinstalled windows, turned off the OS TRIM and immediately ran driver detective and upgraded *every* driver... after which all was well.
Which part of this process solved the problem?
But judging from the forum posts, I'm not the only one who has had to work their way through a similar process.
Is TRIM stable under WIN 7/64?
But with GC working well at the drive firmware level, my conclusion was why bother with TRIM implemented at the OS level, even in non-RAID configurations?
(This was a Dell Vostro 430, i7, Win 7/64 bit system, BTW).
One issue I did find was that in Windows 7 the Corsair drive properly identified itself as an SSD and Windows 7 would not defragment the drive; this OCZ drive apparently does not let Windows know it is an SSD so if you do a defragment it will try to defrag the drive. It's recommended that you do not defrag an SSD - while nothing bad will happen; SSD's don't need defragmentation since there is no platter that files are randomly dropped on - everything can be accessed instantly as the data sits on memory chips.
Great performing drive and I don't notice any heat at all coming from it; I reformatted and put it through a series of tests to make sure it would not freeze or crash on it. So far so good. While expensive it is a great investment and improves productivity as it makes everything run much much faster.
Whether you are using a desktop or laptop this is a pretty good drive to look at purchasing.
I've been using these drives for some time and do not recommend them at this point. I've had to RMA this drive twice, the second time with less than a month usage. I don't defragment or use these drives that heavily but they keep corrupting. I tried installing Windows on the second drive and it allows it then freezes up randomly when using Windows. No freezing occurs when I use a standard hdd or another ssd. I tried to rule out all other hardware on my computer and it always kept coming back to this ssd being the problem. I'm using Windows 7 64-bit so I know the drive is compatible; I just believe the memory used in these drives is cheap and has a high failure rate; especially when I had to RMA a drive after being used for less than a month of light usage. I've picked up an Intel 160gb ssd as a replacement and will see how that goes.
I did run into some challenges migrating my previous HDD's OS load, apps, and data to the new disk. Eventually got it using Acronis True Image Home 2010. I have a blog post series here about my experience if you'd like to know more ([...]).
Overall, great product. My timing was definitely bad, though - it's almost $100 less this week than last (I paid $499).
