The first generation of SSDs had an issue where the drive would become fragmented and loose performance over time. This could also lead to data corruption in severe cases.
Now the issue is with the latest 34nm X25 SSDs. The problem is connected to a very small number of drives becoming corrupted when a BIOS password is used. Still to ensure that this does not become a major issue Intel has suspended shipments of the new drive and are working on a firmware fix for this problem.
