| The HP 505637-001 hard disk 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 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) |
IRAW enhances data protection by verifying-during drive idle time-that data in the drive buffer was properly written. |
