| 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. |
| Features |
Benefits |
| |
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.
|
| |
Distinctions |
- Cheetah 10K.7 is designed and manufactured by the same teams that
successfully delivered the past six award-winning generations of Cheetah.

Note: LW and LC drives do not have internal terminators or
any other way of adding internal terminators to the
drive; use external active termination if required.

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