| |
| The Cheetah 15K.4 is the best performance, lowest cost of ownership, 3.5-inch disc drive. It enables higher performance with fewer drives, while offering the industry's highest reliability. |
 |
Features |
Benefits |
|
15K RPM spindle speed
|
Delivers more I/O's per second than 10K, and faster sustained transfer rates, enabling the same high performance to be met with fewer drives.
|
Background Media Scan
|
Proactively scans the media for potential defects during drive idle time without using system bandwidth. It enables incipient errors to be corrected before data is lost.
|
Enhanced Error Correction Code
|
Better maintains performance throughout the life of the drive and reduces the probability of lost data.
|
Fluid Dynamic Bearing Motor
|
No ball bearings means reduced acoustics and improved reliability.
|
Full Duty Cycle Reliability
|
The Cheetah 15K.4 is designed to have the highest reliability, even when in used in demanding applications around the clock, 365 days per year.
|
Serial Attached SCSI (3 Gb/sec)
|
Serial Attached SCSI (SAS) enables high-performance 15K SAS drives to interoperate with high-capacity NL35 SATA drives helping simplify and consolidate tiered storage.
|
|
Distinctions |
- 30% more IOPS and more than 20% faster response times than 3.5-inch 10K drives
- The industry's highest reliability, with 1,400,000 hour MTBF
