• 7,200-RPM spindle speed

   

   

• 2-Mbyte buffer

   

   

• High instantaneous (burst) data transfer rates (up to 100 Mbytes per second) using Ultra DMA mode 5.

   

   

• Giant magnetoresistive (GMR) recording heads and EPRML TECHNOLOGY, which provide the drives with increased areal density.

   

   

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

   

   

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

   

   

• Quiet operation.

   

   

• 350 Gs nonoperating shock.

   

   

• SeaTools 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 disc drives.

   

   

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

   

   

• Support for Read Multiple and Write Multiple commands.

   

   

• Support for autodetection of master/slave drives that use cable select (CSEL).
