The sixth generation of the award-winning IBM Ultrastar 10,000 RPM disk drive family, IBM Ultrastar 146Z10 drives offer proven quality and superior performance, 8MB multi-segmented buffers, a sophisticated command queuing algorithm, hardware automation,and superior data rates (825 Mbps).Ultrastar 146Z10 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.
