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 |
