Introduction
Overview
The Seagate STT8000 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
(MB/min) without compression. With optimal system resources and
compressible data structures, nominal transfer rates of 60 MB/min can be
observed using software data compression (assumes 2:1 compression ratio).
The system optimizations include but are not limited to
z Allocating the maximum amount of the base 640 KB memory available
z Using a memory manager program
Note: During backup tasks, screen savers can have a negative affect on
transfer rates.
Data compression is available within the Seagate Backup software package for
DOS and Windows and typically provides for 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 TM . 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 (KB/sec). This process maximizes system throughput by
eliminating tape repositioning, which is typically required when the tape drive
operates faster than the host computer.
The product 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.
