I’ve been using a 240GB Intel SSD 520 as my boot drive for about three weeks (Intel RSTe v3.5.1.1009). I have not had any problems with day to day operations and the AS SSD benchmark for the drive is about what I would expect it to be. Yesterday I attempted to optimize the drive using Intel SSD Toolbox v3.1.2. At 85% I got a BSOD that completely froze the system. I did a hard reboot and the system came up without an issue. All of the trim files created by SSD Toolbox were still on the drive. I deleted them manually and attempted to optimize the drive again. The result was the same. Except this time when I restarted the system the SSD boot drive could not be found. The second time I tried to turn the computer on the SSD drive was found and the system booted. I ran SSD Toolbox quick and full diagnostic scans and neither found a problem with the drive. I also ran optimize on an X25-M SSD drive I also have in my system and it completed without a problem.
Although the drive seems to be working fine, the fact that running optimize crashes the system has me concerned with its long-term reliability. Any suggestions for further troubleshooting the problem (or fixing it) would be greatly appreciated.
