Summary: This SSD has a tone of corrupt sectors after 1.5 years. It was the TOP SSD with rave reviews, the problem is that most of rave reviews are written by the honeymooner. Of course a SSD is nice and fast when it's first installed, but this one doesn't seem to age well.
Summary: Bought an M4 as a secondary drive - now reconsidering that move.
Pros: Great while it worked....BIOS updates are painless, unlike other vendors who have long drawn out update schemes for boot drives....
Cons: After just under 22 months of use, it mysteriously stopped showing up in POST, and being the Boot drive, sorta makes the computer a rather large doorstop. Did the chat support with Crucial (Don't waste your time) and ended up calling them - their servers were down and they said when they come back up, they have some magic way to reset the controller in a non-destructive fashion which has a 98% recovery record.....Let's see if the guy gets back to me when they unbreak ...
Pros: These have been awesome. I bought them a year ago for raid 0 and they have been nearly flawless. No degradation, no stutters, nothing. I set them up on Sata II R0 to get better speeds than Sata III, since Sata III didn't have proper raid support -- no fault of Crucial, it's a motherboard thing.
Cons: Not really a con. With all SSD's it's important to update your firmware and set up Windows to treat your SSD's properly to prevent degradation. Many of the problems you see are likely a result of that. The only con here is price. Two of these were a thousand dollar bomb, and there are cheaper drives available now of better performance. Still, I commend Crucial for these, they were the best at the time and are still treating me well. At this level of performance, "more...
Summary: The drive worked for 6 months and stopped working. I sent the drive back to Crucial and get a refurbished one which worked for 1 months and stopped working. I sent the drive back to Crucial and get a refurbished one. When I tried to clone my existing drive to the SSD, I got "cannot write sector" error. I called Crucial and the support people said she could not provide support because I was not using Crucial to do the transfer and she offered to sell me one!!
Summary: Crucial support is better than others... however they said it would be 8-12 weeks for them to fix this and or give me a new one. They said they would ship me a new drive however they would charge me full price "if" the problem wasn't covered under warranty.
Pros: Purchased the drive in summer of 2010. Drive was lightning fast for about a year
Cons: during the last few months areas of the drive have become corrupt and the drive pauses about once every 5 to 10 seconds causing the system to pause.
Summary: I've been using this as my Windows 7 boot drive for 6 months, with no problems. It's more space than I currently need, however I wanted a drive that would last me for several years without worrying about space limitations. Update 5/30/2013: I've been using for about two years with no problems.
Performance and reliability - you get what you pay for

Summary: I own two of these units - one is my primary boot drive, the other is my primary cache for windows and Photoshop. I had to buy a separate 6 GB/s interface card (Koutech IO-PESA230) [no problems with this card/and 2 drives, BTW] even though my mobo (ASUS Tigershark) had an on-board 6 GB/s connection that I was using for my SAS array.
Pros: I got these units (I own two) for speed and reliability as well as silence. The speed and reliability are unquestionable - my Win7 box boots quickly and w/o any glitches so that I almost forget it's Win7. The second unit serves as a primary Photoshop cache - it makes Photoshop a true production tool w/o waits for transforms, color changes or puppet wraps.
Cons: Price? Long term reliability? I have owned these units for more than a year, so I'm waiting for the built-in warranty clock to tick over (not really - that's something in Detroit and iStuff, yes?). I expect to use these for a long time - years - and I have gotten my money's worth in a year of fast boots and excellent Photoshop response.
Summary: Very nice. I own a bunch of SSD hard drives for various computer rigs, I got this one for my father in laws computer and it has been running great for 6 plus months now. make sure you disable disk defrag and also make sure you dont fill the drive up 100% with data (set a hard drive qouta leaving 6GB free)
