What I'm worried about is the severity of those bugs, and the amount and quality of testing that has gone into these products. > BTW, what OCZ did to increase speed was to increase the cache size in > their large capacity high end Vertex models.

Might make it go faster, definitely wont make it safer. -- Jens Axboe
