Features Benefits
spacer
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.


Compatibility

This drive is compatible with and of our hot swap drive trays.
