Introduction
This manual describes the functional, mechanical and interface specifi-
cations for the ST380020ACE, ST360020ACE, ST340810ACE and the
ST320410ACE. These drives provide the following key features:
•8.9 msec seek time, 5,400-RPM and 2-Mbyte buffer combine for
excellent desktop performance
•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
•The innovative, shock-absorbing SeaShield®cover protects the drive
against electrostatic discharge (ESD) and other handling damage. It
also includes installation instructions and jumper settings.
•SeaToolsdiagnosticsoftwareperformsadrive 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)
