Seagate Cheetah 15K.4 36GB 15K U320 68pin SCSI Hard Drive - Refurbished OEM
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.
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.
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.
