Did you know?
6 Gbps SAS 2.0 technology has been introduced to address data off-load bottlenecks in the direct-access
storage environment. This new throughput doubles the transfer rate of the previous generation. SAS 2.0 is
designed for backward compatibility with 3 Gbps SAS as well as with 3 Gbps SATA hard drives.
Self-encrypting drives are based on a new technology that helps prevent data from being accessed without
authorization. These drives adhere to the Trusted Computing Group (TCG) Enterprise Security Subsystem
Class specification and are National Security Agency qualified to provide government-grade encryption.
With self-encrypting drives (SEDs), if a drive is removed from its storage system or the server that it is
housed in, the data on that drive is encrypted and useless to anyone who attempts to access it without the
appropriate security authorization.
