ST320014A Product Manual, Rev. B 1

Introduction

This manual describes the functional, mechanical and interface specifi-

cations for the ST320014A. This drive provides the following key fea-

tures:

•Low power consumption

•High instantaneous (burst) data-transfer rates (up to 100 Mbytes per

second) using Ultra DMA mode 5

•Giant magnetoresistive (GMR) recording heads and GPRML technol-

ogy, 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

•SeaToolsdiagnostic softwareperformsadrive self-test thateliminates

unnecessary drive returns.

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

•Support for drive self-test (DST) with S.M.A.R.T. Execute Off-line

Immediate

•Support for Read Multiple and Write Multiple commands

•Support for autodetection of master/slave drives that use cable select

(CSEL)
