About Citadel M.2 2280 2TB SSD SATA (DIG-M2S420006)

Citadel FIPS-certified self-encrypting SSDs are the only SSDs to offer pre-tested and pre-integrated multi-factor authentication and pre-boot authentication (PBA).

This secured data is encrypted by NSA-approved Advanced Encryption Standard (AES) 256-bit encryption at the hardware level. Once booted, Citadel allows no-overhead, hardware-speed access to encrypted data at the full performance of the system.
