The Intel 520 SSD series does not support 256-bit AES encryption

Intel was forced to change previous specifications due to a bug in the SandForce SF-2281. All SandForce SF-2000 series controllers are involved.

Due to an error in the SandForce SF-2281 controller, 520-bit AES encryption is not supported on Intel 256 series drives, but the 128-bit procedure can still be used securely. It is worth noting that this is not an individual case. In addition to Intel, Kingston has already indicated that the specifications for the SSDNow V + 200 and KC100 models have changed. Although not a critical error, the two companies are willing to exchange problematic products. Those who purchased an Intel 520 Series SSD before July 1st can reclaim the purchase price until October XNUMXst.

Losing 256-bit AES encryption is practically not a big deal - it can cause problems in some individual cases - but the bug cannot be fixed with a firmware update, so users can legitimately complain.
