Seagate Cheetah 10K.7 73GB 10K U320 68pin SCSI Hard Drive - Seagate Factory Recertified
|The Cheetah 10K.7 lowers cost of ownership with the industry's highest 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.|
|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.|
|Low Power and Cooling Requirements||Further reduces cost of ownership|
|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.|
|Fluid Dynamic Bearing Motor||No ball bearings means reduced acoustics and improved reliability.|
