SEAGATE LAPTOP THIN HDD PRODUCT MANUAL, REV. K 2
1.0 Introduction
This manual describes the functional, mechanical and interface specifications for the following Seagate
®
Laptop Thin HDD model drives:
For more information on SED drives see About (SED) Self-Encrypting Drives on page 20.
For more information on FIPS 140-2 Level 2 certification see About FIPS
on page 19.
These drives provide the following key features:
 5400-RPM spindle speed.
 16MB buffer.
 Quiet operation. Fluid Dynamic Bearing (FDB) motor.
 High instantaneous (burst) data-transfer rates (up to 6Gb/s).
 Perpendicular recording technology.
 State-of-the-art cache and on-the-fly error-correction algorithms.
 Native Command Queuing (NCQ) with command ordering.
 Full-track multiple-sector transfer capability without local processor intervention.
 1000 Gs nonoperating shock and 400 Gs of operating shock.
 SeaTools
TM
diagnostic software performs a drive self-test that eliminates unnecessary drive returns.
 The 3D Defense System™, which includes Drive Defense, Data Defense and Diagnostic Defense,
offers the industry’s most comprehensive protection for disk drives.
 Support for S.M.A.R.T. drive monitoring and reporting.
 Support for Read Multiple and Write Multiple commands.
 Worldwide Name (WWN) capability uniquely identifies the drive.
Laptop Thin Self-Encrypting Drive models have the following additional features
 Automatic data encryption/decryption
 Controlled access
 Random number generator
 Drive locking
 16 independent data bands
 Cryptographic erase of user data for a drive that will be repurposed or scrapped
 Authenticated firmware download.
There is no significant performance difference between Self-Encrypting Drive and standard (non-Self-Encrypting Drive) models.

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 encryption was necessary.
