Description

Seagate Cheetah 15K.4 73GB 15K U320 80pin SCA-2 SCSI Hard Drive ST373454LC - Brand New

The Cheetah 15K.4 is the best performance, lowest cost of ownership, 3.5-inch disc drive. It enables higher performance with fewer drives, while offering the industry's highest reliability.

 

Features

Benefits

 

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.
 

Ultra320 SCSI
 

Up to 320 Mbyte-per-second throughput and faster sustained transfer rate
 

Background Media Scan
 

Proactively scans the media for potential defects during drive idle time without using system bandwidth. It enables incipient errors to be corrected before data is lost.
 

Enhanced Error Correction Code
 

Better maintains performance throughout the life of the drive and reduces the probability of lost data.
 

Fluid Dynamic Bearing Motor
 

No ball bearings means reduced acoustics and improved reliability.
 

Full Duty Cycle Reliability
 

The Cheetah 15K.4 is designed to have the highest reliability, even when in used in demanding applications around the clock, 365 days per year.
 

 


Distinctions

  • 30% more IOPS and more than 20% faster response times than 3.5-inch 10K drives

  • The industry's highest reliability, with 1,400,000 hour MTBF
