IBM - Hard drive - 146.8 GB - internal - 3.5" - 10000 rpm - buffer: 8 MB, P/N 08K0362 The IBM Ultrastar 146Z10 drive family features more powerful processors and read/write channels to excel in server-class environments. The drives combine fast seek times, large 8 MB multi-segmented buffers, a sophisticated command queuing algorithm, hardware automation, and superior data rates (825 Mbps). Ultrastar 146Z10 drives include a servo technology (Rotational Vibration Safeguard "RVS"), employed to counteract the effects of rotational vibration that commonly occur in multi-drive cabinets. Employ a fifth-generation giant magnetoresistive (GMR) head technology to double areal density from previous generation drives (26.3 Gbits/sq.in.) and boost performance. Highly efficient No-ID sector formatting enables more data to be stored per disk.
