SandForce SF-2000 encryption flaw discovered

SandForce's SF-2000 SSD controller has been found to limit encryption to AES-128, rather than the AES-256 originally claimed.

doesnt seem that serious of a flaw. although would be interesting to see if this was a coverup

Both companies are right to say that AES-128 is still pretty damn secure, but looking at it mathematically for a moment: the keyspace of AES-128 is one 340,282,366,920,938,463,463,374,607,431,768,211,45 6th that of AES-256. They're both damn secure, but one is *significantly* more secure than the other.

Or they use a proprietary encryption layer on top of the drive, rather than built in encryption in the SSD itself.

Possibly, but it offers a keyspace 340 trillion trillion trillion times smaller than 256 bit.
