The Seagate Cheetah
36ES Series 18.4GB Ultra160 SCSI hard drive features a 10,000rpm
spindle speed, 5.2ms access time, a 4MB cache buffer, and a
five year manufacturer's warranty. The Cheetah 36ES benefits
from significant performance enhancements with Seagate's Advanced
Multidrive System (SAMS) that optimizes performance in server
and RAID applications, and G-Force Protection, a drive enhancement
that protects the drive's data from external shock.
The Ultra 160 SCSI hard drives are capable of external I/O
data transfer rates up to 160MB/second, they have a 68-pin
connector, and they work on Wide, Ultra Wide, Ultra2, or Ultra
160 controllers at the controller's maximum speed. To achieve
160MB/sec burst transfer rate, an Ultra160 SCSI controller
card is required.
The Cheetah 36ES comes assembled in our high quality external
enclosure and is tested at our facility. The enclosure features
two standard Ultra 160 SCSI 68-pin external connectors, a
40 Watt power supply, a cooling fan, a 16 position SCSI ID
switch, and an Ultra 160 active terminator. Case dimensions
are 2.7" x 8.25" x 11". For this external hard
drive, you will need an external SCSI cable.
