All Viking SSDs are self-encrypting drives (SEDs). An SED’s Bulk Data Encryption feature provides automatic hardware-based data security and enhanced secure erase capability. The SED scrambles and descrambles data using a data encryption key as it is written or read, giving the highest level of data protection available and providing a fast erase simply by deleting the encryption key, thereby eliminating the need for time consuming data-overwrites. Data on the drive is instantly rendered unreadable. ATA Secure Erase is a feature from the Trusted Computing Group (TCG) security enhancements used in enterprise-class SSDs, which offers back-end security, IP protection, and is always on with unique key.
