Kingston has announced that their SSD drives using the Sandforce SF-2000 family of controllers runs 128-bit AES encryption, rather than the 256 bit level encryption that they have been advertising. This seems to be a flaw in the Sandforce controllers themselves. Kingston is offering direct replacements for those customers who require the 256 bit encryption protection.
The Kingston press release is here.
Intel has also released a statement and confirmed this finding. They are currently offering full refunds for those customers who have purchased the Intel 520 series of SSD's and who require 256 bit AES encryption. This offer is good through October 1, 2012.
