Summary: I bought this SSD drive because of [...] reviews. However, this SSD drive released a firmware update on 1/4/2011 that very few consumers can install. ADATA omitted a number of key settings that are required before an update can be done. After following those changes, the firmware update failed repeatedly. My cumputer would often freeze-up. After making repeated calls to ADATA about this problem, they wanted me to ship the drive to them.
Summary: I purchased my ADATA S599 drive in late October and had it running in my Windows 7 x64 system until yesterday. While it was operational I noticed faster transfer speeds and better Windows Experience Index for my system. I was happy with the drive's performance. Problems began when I tried to upgrade the drive to a newer firmware just released. The drive just wouldn't upgrade.
