Seagate LD25 Series 5400.2 drives are 2.5-inch form factor products designed for non-notebook PC applica- tions such as:

•Consumer electronics (gaming, small personal video recorders (PVRs) and digital video recorders (DVRs)

•Ultra-small desktop PCs

•Internet appliances

•Printers, copiers, and other devices that may use disc drives for data storage

LD25 Series 5400.2 drives are quieter, lighter and use less power than 3.5-inch drives. They are ideal for appli- cations requiring the form and fit of a notebook drive but without some of the design specifications required by notebook drives such as high shock tolerance, high performance, and power management. LD25 Series drives are not presently suited for notebook applications or other environments with high operating temperatures.

These drives provide the following key features:

•5,400-RPM spindle speed

•2-Mbyte buffer

•High instantaneous (burst) data transfer rates

•Perpendicular recording and Tunneling Magnetoresistive (TMR) recording heads

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

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

•Quiet operation

•500 Gs nonoperating shock

•The 3D Defense System™ (Drive Defense, Data Defense, and Diagnostic Defense) provides the industry’s most comprehensive protection for disc drives

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

•Support for Read Multiple and Write Multiple commands
