1.0 Introduction

This manual describes the functional, mechanical and interface specifications for the following Seagate

U Series 9® model drives:

• ST3160022A

• ST3120025A

• ST380012A

These drives provide the following key features:

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

• Giant magnetoresistive (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.

• Quiet operation.

• 350 Gs nonoperating shock.

• SeaTools diagnostic software performs a drive self-test that eliminates unnecessary drive returns.

• The 3D Defense System™ , which includes Drive Defe nse, Data Defense, and Diag nostic Defense, offers the industry’s most comprehensive protection for disc drives.

• 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).

2.7 Seek time

Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive diagnostics. The specifications in the table below are defined as follows:

• Track-to-track seek time is an average of all possible single-track seeks in both directions.

• Average seek time is a true statistical random av erage of at least 5,000 measurements of seeks betwee n random tracks, less overhead.

T ypic al see k times (mse c) Read Write

Track-to-track <1.0 <1.2 Average 8.5 9.5 Average latency: 4.16 4.16

Note. These drives are designed to consistently meet the seek times represented in this manual. Physical

seeks, regardle ss of mode ( such as track- to-track and average), are ex pected to meet or exceed the noted values. However, due to the manne r in which these drives are formatted, benchma rk tests that include command overhead or measure logical seeks may produce results that vary from these specifications.

2.8 Start/stop times

Power-on to Ready (sec) 10 (max) Standby to Ready (sec) 10 (max) Ready to spindle stop (sec) 20 (max)

2.9 Power specifications

The drive receives DC power (+5V or +12V) through a four-pin standard drive power connector.
