ST3400820A	ST3250820A	ST3120215A
ST3400620A	ST3250620A	ST380815A

These drives provide the following key features:

•7,200-RPM spindle speed

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

•Perpendicular recording and Tunneling Magnetoresistive (TMR) recording heads for 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.

•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).
