Summary: I purchased the 256GB drive and formatted it and installed windows 7 flawlessly. The drive works the way is supposed to. I tested the speed of the drive and i am only getting about 250MB/s data transfer, but that is only because i have an older motherboard that is limiting the full potential speed of the SSD drive. Still, my system has improved at boot up and when opening programs mostly.
Summary: I am not new to SSD's. I have a Crucial M4 in my other PC build and it outperforms this one. The M4 claims to have a sequential write speen of 175mb/s and when I ran a benchmark I got 169mb/s...pretty close. This one claimed to have a write speed of "up to" 505 mb/s and I thought, "wow...this thing is a steal!" Well when I ran a benchmark I got a disappointing 67 mb/s (100mb/s slower then the M4 that claimed less write speed and way lower then it claimed itself).
Summary: I wish that i had sata3 instead of sata2, but this still sped boot time up considerably. I also bought one for the wife's computer. The cloning software could have been better. I did not want to clone the recovery partition, but I had no choice but to do so.
Summary: I have replaced a few drives with SSD's and chose this drive, first to replace my son's hard drive, then I recently rebuilt a 6 year old Macbook with one of these and a bunch more RAM and it compares with my $1800 dell ultrabook! A GREAT INVESTMENT! I may add another and set up a RAID.
Summary: Solid SSD. I didn't do any bench-marking but my Windows 7 Ultimate starts up within 10-15 seconds (the windows logo barely starts its animation before I'm moved to the welcome screen). Loads up games amazingly fast too! (I have Planetside 2 installed on this SSD and it loads up super fast.
Summary: I use this little guy to run my OS, drivers, and other small apps on my Gaming PC. IT runs great, no problems so far. 128GB doesn't go as far as it use to though. I am approaching half capacity already. 3 year warranty is very encouraging. Great way to take some heat out of your Build and add some serious speed, over HDD anyways.
