Intel 320 SSD bug causes forum despair
 

Users are reporting that Intel 320 SSDs are dying, and power cycle limitations appear to be at fault. The company had not issued a fix at time of writing.

Be wary of the new Intel SSD 320 series. Currently, there's a bug in the controller that can cause the device to revert to 8MB during a power failure. AFAIK they have not yet publicly announced it, and won't have a firmware fix ready for release until the end of July.
