AES-128 Data Encryption and Secure Erase
Upon initialization of the SF-2281 series SSD, an internal randomly generated AES-128 encryption key is generated in the controller. This
encryption key is not externally accessible, which ensures integrity of the encryption key and the data that it protects. This key is then
used to encrypt all data being written to the flash. Only encrypted data is written to the physical NAND flash chips, which ensures that
any data pulled straight from the NAND flash chips is undecipherable to unauthorized parties. When an ATA Secure Erase command is
sent to the drive, the controller erases and resets the internal encryption key, rendering the data in the NAND flash undecipherable. The
data allocation map data, all LBAs and SMART logs are also erased. The Secure Erase process takes less than 4 seconds to complete,
regardess of capacity. After the Secure Erase is completed, the drive is still functional, but the old existing data is unrecoverable.
