Only time will tell if this is real fix.
Mine is stable so far. But then again after much fudging around, I have had my OCZ drive stable for the last couple of releases. What gets me though is how much time OCZ's support reps have spent in their support forums pointing the finger at Intel as the source of the problem and going to great lengths to explain that it couldn't be fixed with a firmware update. It was Intel's fault.
Now suddenly we have the magic firmware update?????
