• 7,200-RPM spindle speed
• High instantaneous (burst) data transfer rates (up to 100 Mbytes per second) using Ultra DMA mode 5.
• Tunneling Giant magnetoresistive (TGMR) 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.
• 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).
