Note. Previous generations of Seagate Self-Encrypting Drive models were called Full Disk Encryption (FDE) models before a differentiation between drive-based encryption and other forms of encryp- tion was necessary.

Note. The Self-Encrypting Drive models indicated on the cover of this product manual have provisions for “Security of Data at Rest” based on the standards defined by the Trusted Computing Group (see www.trustedcomputinggroup.org).

For more information on FIPS 140-2 Level 2 certification see See Section 5.0 on page 29.

These drives provide the following key features:

•7200 RPM spindle speed.

•High instantaneous (burst) data-transfer rates (up to 600MB/s).

•Perpendicular recording technology provides the drives with increased areal density.

•State-of-the-art cache and on-the-fly error-correction algorithms.

•Native Command Queueing with command ordering to increase performance in demanding applications.

•Full-track multiple-sector transfer capability without local processor intervention.

•Quiet operation.

•SeaTools diagnostic software performs a drive self-test that eliminates unnecessary drive returns.

•Support for S.M.A.R.T. drive monitoring and reporting.

•Supports latching SATA cables and connectors.

•Worldwide Name (WWN) capability uniquely identifies the drive.
