Seagate ST3146707LC SCSI Hard Drives

Seagate Cheetah 10K.7 146GB 10K U320 80pin SCA-2 SCSI Hard Drive - Brand New 5 Year Warranty

The Cheetah 10K.7 lowers cost of ownership with the industry'shighest reliability, designed for full duty cycle applications; Seagate-exclusive Background Media Scan; enhanced Error Correction Code; and low power and cooling requirements. Capacities include 300, 146 and 73 Gbytes, with Ultra320 SCSI or 2 Gbit/sec Fibre Channel interfaces.
Features	Benefits
Highest Reliablity Rating	Reliability has a significant influence on a disc drive's total cost of ownership. Cheetah 10K.7 has an 0.62 percent AFR, the best in the industry.
Full Duty Cycle Reliability	The Cheetah 10K.7 is designed to have the highest reliability, even when in used in demanding applications around the clock, 365 days per year.
Background Media Scan	Background Media Scan, a Seagate-exclusive feature, scans the media during drive idle time to preserve system bandwidth while enabling incipient errors to be corrected before data is lost.
Enhanced Error Correction Code	Decreased bit error rate better maintains performance throughout the life of the drive and results in a lower probability of lost data.
Fluid Dynamic Bearing Motor	No ball bearings means reduced acoustics and improved reliability.
Low Power and Cooling Requirements	Further reduces cost of ownership
Distinctions
Cheetah 10K.7 is designed and manufactured by the same teams that delivered the past six award-winning generations of Cheetah.
