| The Cheetah 15K.5 is mainstream enterprise disc drive storage. It is the best price/performance, lowest cost of ownership, 3.5-inch disc drive, with the industry's highest 3.5" disc drive reliability. | | Features |
Benefits |
15K RPM spindle speed
|
Delivers more I/O's per second and faster sustained transfer rates than 10K 3.5-inch drvies, enabling the same high performance to be met with fewer drives.
|
Background Media Scan (BMS)
|
Second generation Seagate-exclusive BMS proactively scans the media for potential defects during drive idle time. It enables incipient errors to be corrected before data is lost.
|
Perpendicular Recording
|
Perpendicular recording is fundamentally superior, enabling the highest areal density with 30 percent higher performance.
|
Nonrecoverable Error Rate
|
The nonrecoverable error rate has been improved by a factor of 10.
|
Idle Read After Write (IRAW)
|
Seagate-exclusive IRAW enhances data protection by verifying-during drive idle time-that data in the drive buffer was properly written.
|
- The industry's highest reliability 3.5" drive
- 30% more IOPS and 20% faster response times than 3.5" 10K drives
|
