Introduction
This manual describes the functional, mechanical and interface specifications for the ST31013A, ST3 2111A, ST33223A and the ST 34323A.
These drives provide the following key features:
•
Low power consumption
•
Quiet operation
•
Support for (S.M.A.R.T.) self-monitoring, analysis and reporting technology for drives.
•
High instantaneous (burst) data-transfer rates (up to 33.3 Mbytes per
second) using Ultra DMA mode 2
•
Full-track multiple-sector transfer capability without local processor
intervention
•
128-Kbyte cache
•
State-of-the-art cache and on-the-fly error-correction algorithms
•
Support for Read Multiple and Write Multiple commands
•
Support for autodetection of master/slave drives that use cable select
(CSEL)
•
These drives use MR recordi ng heads and PRML technology , which
provide the drives with increased areal density.
