			Overview
Introducing the sixth generation of Ultrastar 10,000 rpm disk drives. The Hitachi Ultrastar 146 Z10 drive offers high quality and superior performance. The drives feature more powerful processors and read/write channels to excel in server-class environments. To achieve maximum I/O performance, the drives combine fast seek times, large 8MB 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. Reliability features The Ultrastar 146 Z10 is a server class drive that incorporates storage breakthrough technology—antiferro magnetically coupled (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). In addition, load/unload technology and glass substrate disks increase reliability of Ultrastar drives by providing a more robust solution at high rotational speeds. Outstanding environmentals Hitachi Ultrastar drives provide extremely quiet operation. The tri-laminate drive cover reduces both idle and seek acoustics while an enhanced spindle motor driver enables smoother commutation for less noise. Moreover, the Ultrastar 146 Z10 delivers an outstanding power efficient design. Product Search:
