The Cheetah 15K.3 is the lowest cost of ownership 15K drive, and the lowest cost-per-I/O disc drive ever. It is fast, cool, and quiet, and has the highest reliability rating in the industry.

Features

3D Defense System
The most comprehensive drive protection system in the industry, consisting of Drive Defense, Data Defense and Diagnostic Defense.

SeaShell
Seagate's revolutionary packaging protects the drive from external shock.

SAMS
Seagate's Advanced Multidrive System optimizes the drive for maximum I/O performance in Multidrive environments.

JIT
Just-In-Time minimizes actuator impact on power, vibration and acoustics.

Ultra320 SCSI
Up to 320-Mbyte/sec transfer rate; Includes Packetization and QAS. Backward compatible with Ultra160. Cables 15 devices, up to 12 meters.

15K RPM spindle speed
Delivers more I/O's per second than 10K, and faster sustained transfer rates, enabling the same high performance to be met with fewer drives.
