When SandForce announced the SF-2000 SSD controller family, it touted the controller's ability to encrypt data with a 256-bit AES algorithm. The previous generation of SandForce controllers did 128-bit AES encryption, but the new chip added a second hardware engine with AES-256 support. Trouble is, the SF-2000 controller's 256-bit encryption doesn't work properly. Although the latest SandForce controllers encrypt data using AES, they do so using only 128 bits.
We just got off the phone with SandForce, who we contacted in order to better understand this issue. A company representative told us the SF-2000 controllers retained their AES-128 support because the US government doesn't allow products with 256-bit encryption to be sold to some countries. Sounds like the mechanism that determines whether ...
