2.6 Data Security

Viking’s Slim SATA SSD’s are self-encrypting drives (SED), with a bulk data encryption feature that provides automatic hardware-based data security and enhanced secure erase capability.

A self-encrypting drive, scrambles data using a data encryption key as it is written to the drive and then descrambles it with the key as it is retrieved. This gives the user the highest level of data protection available and provides a fast erase simply by deleting the encryption key, eliminating the need for time consuming data-overwrite. Data on the drive is instantly rendered unreadable.

The Slim SATA SSD supports AES-128 encryption, AES-256 encryption and ATA Secure Erase features to protect sensitive data. The drive is also available with TCG security enhancements.
