Introduction

Drive overview

The Seagate STT8000A ATAPI minicartridge drive extends the Seagate family of

one-inch high, DC2000 drives that feature high performance, high reliability, and

quiet operation. The drive transfers data at up to 36 megabytes per minute

(Mbytes/min) without compression. With optimal system resources and

compressible data structures, nominal transfer rates of up to 60 Mbytes/min can be

observed using software data compression (assumes 2:1 compression ratio).

Data compression is available within the Seagate Backup software package for

DOS and Windows and typically provides for up to a 2:1 compression ratio. The

compression ratio is dependent on the specific system and the nature of the files

being compressed.

This drive optimizes throughput through the Seagate feature FastSense

. This

feature enables the drive to automatically sense the fastest supportable data

transfer rate of the host system and choose a transfer speed of either 600, 450, or

300 kilobytes/second (Kbyte/sec). This process maximizes system throughput by

eliminating tape repositioning, which is typically required when the tape drive

operates faster than the host computer.

This drive is available as an internal device in either a 3.5-inch or half-high 5.25-inch

configuration. The drive form factors are tailored for easy installation in today's

computers.

The drive supports the QIC-3095 format standard and will provide 4 gigabytes

uncompressed storage capacity, 8 gigabytes compressed, with a Travan TR-4

cartridge.

The drive will also write and read tapes conforming to the QIC-3080 standard,

providing 1.6 and 2.0 gigabytes respectively on 400 foot minicartridges or 400 foot

QIC-Wide cartridges.

A precision burst intelligent positioning system is used to achieve high track

densities.
