To achieve maximum I/O performance, this IBM-Hitachi 36-GB SCSI hard drive combines fast seek times, large 8 MB multi-segmented buffers, a sophisticated command queuing algorithm, hardware automation, and superior data rates (825 Mbps). Ultrastar 146 Z10 drives include new servo technology (Rotational Vibration Safeguard "RVS"), employed to counteract the effects of rotational vibration that commonly occur in multi-drive cabinets. They also employ fifth-generation giant magnetoresistive (GMR) head technology to double areal density from previous generation drives (26.3 Gbits/sq. in.) and boost performance. In addition, highly efficient No-ID sector formatting enables more data to be stored per disk.

The Ultrastar 146 Z10 family of serverclass drives is the first of its class to incorporate our storage breakthrough technology - antiferromagneticallycoupled (AFC) media. Informally known as "pixie dust", this technology sandwiches a three-atom thick layer of ruthenium, a precious metal, between two magnetic layers on a disk. AFC technology provides greater stability of the recording media, enhancing reliability.

Drive Fitness Test enables drive selftesting and analysis - for more robust system management. To help ensure data protection, Hitachi Ultrastar drives include exclusive reporting tools, such as Predictive Failure Analysis (to signal potential drive problems) and Drive-TIP (to monitor the drive temperature and avoid malfunctions).

Hitachi Ultrastar drives provide high data throughput for data-intensive applications with a choice of 2 Gbit Fibre Channel and Ultra320 SCSI (backwardcompatible) interfaces. The Ultra320 SCSI adds greater speed, reduced overhead, improved diagnostic capabilities and data protection.
