Summary: I purchased this disk over a year ago and have been running it in an XBMC machine connected to my TV and the system ran strong for a number of months before the PC started locking up and needed to be reset each time this happened it forced a check disk. On further investigation there was a number of errors showing up on the SMART tests so logged this with Crucial and they have replaced the disk.
Summary: Mine failed after about 6 months. Although I lack the knowledge to identify the problem, SMART diagnostics showed no faults, but various disk checks repeatedly showed corruptions, my linux OS kept corrupting beyond repair, and ultimately I got the disk refunded and bought a Sandisk SSD.
Summary: Like some other reviewers I didn't buy this drive off Amazon so the purpose is not to knock their service; however, be warned that, as others have said, this drive is flaky at best. Installed easily on my home, lightly-used Ubuntu desktop. First impressions were that boot times were decent & as expected, but the 'laggy' performance during use is a pain in the backside.
Summary: I think a few people have bought these drives expecting something they're not; these drives are very much budget SSDs without the kind of performance of more powerful units. If all you want is to give your system a bit of a boost, then this drive will probably do that just fine, but with a few caveats. Firstly, the drive's read/write performance for single files is extremely good (easily 200mb/sec read, and close to that for write).
Summary: While I initially thought this drive was plenty fast for it's price, my enthusiasm waned after 4 months of light use when one day: CAM status: ATA Status Error ATA status: 41 (DRDY ERR), error: 40 (UNC ) RES: 41 40 00 1e 54 00 00 00 00 00 01 Turns out the drive had lost about half the data on it to unrecoverable read errors.
