HDD Seagate Cheetah 15K3 ST336753FCV, 36.7GB, 15K rpm, 16MB Cache, Fibre Channel (FC-AL) 40-pin, OEM (жесткий диск)

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

Benefits

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.
 

Distinctions

• Extremely low power consumption allows easy integration for high performance.

• 1,200,000-hour MTBF

ST336753FC drives have two independent FC-AL ports. These
  ports may be connected on independent loops or on the same
  loop.  Port A and Port B may be connected in any order or
  combination.
