FeaturesBenefits
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.
