Introduction

This manual describes the functional, mechanical and interface specifi-

cations for the ST328040A, ST327240A, ST320430A, ST313620A,

ST310220A, and the ST36810A. These drives provide the following key

features:

•Low power consumption

•Quiet operation

•High instantaneous (burst) data-transfer rates (up to 66.6 Mbytes per

second) using Ultra DMA mode 4

•7,200-RPM and 512-Kbyte buffer combine for superior desktop per-

formance

•300 Gs nonoperating shock

•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

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

•Support for Read Multiple and Write Multiple commands
