Summary: This is the first SSD drive I have used in a system. It boots Windows 7 (64-bit) in less than 15 seconds, which is longer than my system takes to pass through the BIOS. I had no trouble installing the drive and loading Windows 7. But I have had some issues with this drive. I started getting the Windows BSOD about once every 3 or 4 days, each time my system would not find the ADATA drive until I powered off the system and restarted the system.
