User manual HITACHI ULTRASTAR 36LP DATASHEET

[. . . ] Reliable, cost-effective storage for workstations, high-performance desktop systems, and LAN and enterprise servers IBM Ultrastar 36LP hard disk drive Highlights Capacities of 36, 18, and 9 GB and an areal density of 6. 4 Gbits/sq. provide superior data storage in a low-profile drive. [. . . ] Maximum reliability To help ensure the maximum data protection possible, IBM Ultrastar drives include IBM-exclusive reporting tools, such as Predictive Failure Analysis* (to alert users about potential drive problems) and Drive-TIP* (to monitor drive temperatures and avoid malfunctions). Reliability is further enhanced through load/unload technology, glass substrate disks, and active damping, which stabilizes head movement even under extreme conditions. Together, these technologies provide a more robust solution. In addition, IBM Ultrastar drives have fewer components than other drives, a factor that reduces the possibility of component failure. Outstanding environmentals An efficient electronic design enables low power requirements. Exclusive enhanced power standby modes are triggered by read/write inactivity to help minimize power use. Excellent acoustics enable quiet operation, which is essential for workstation environments. Advanced interfaces IBM Ultrastar 36LP drives support Ultra2 SCSI and Ultra160 SCSI interfaces.
