All About Self-Encrypting Drives

Aug 12, 2014

With data security risks on the rise, an influx of government mandates and regulations for securing data have been implemented and are becoming part of the corporate landscape. Eliminating exposure of private data is now simply viewed as a mandatory and sound business practice.

To avoid the high costs associated with these types of data compromises, organizations must put in place a comprehensive security strategy. While each point in the storage infrastructure provides unique threat models, data-at-rest presents one of the highest security vulnerabilities. Data spends most of its life at rest on drives within a system, and the drives will eventually leave, either for repair, retirement, relocation or maintenance. It is at this time that drives—and the data contained on them—are most vulnerable to being lost or stolen.

Server and data center storage drives need to protect the drive from unauthorized access to data, and one of the best methods is hardware encryption. HGST’s Self Encrypting Drive (SED) is one method of implementing encryption circuitry directly on the SSD. Designed with hardware-based encryption support, HGST SEDs will encrypt everything written to the drive, and de-crypt everything read from the drive.
