1 Year Reseller - What does this mean?
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

  • Cheetah 10K.7 is designed and manufactured by the same teams that delivered the past six award-winning generations of Cheetah.

           Use active (ANSI SCSI-2 Alternative 2) terminators
           when terminating the bus.  Use active negation
           terminators when terminating a SCSI Ultra2 bus
           operating in Low Voltage Differential (LVD) mode.
