The SF2400 flash controller features high-level security protocols for the safety of data stored in flash memory. Seagate DuraClass technology automatically stores data in a highly secure AES-256 and AES-128 hardware encrypted format, that double encrypts the data. SSDs using SandForce controllers are self-encrypting devices (SED) providing the highest level of data security.1 Data Protection and Reliability The SF2400 flash controller features a superior higher-level BCH ECC algorithm with double the standard ECC correction power above the NAND flash required specification, and the unique Seagate RAISE™ (Redundant Array of Independent Silicon Elements) technology. RAISE technology provides the protection and reliability of RAID on a single drive without the 2x write overhead of parity.
