Enterprise 20-Pack SAS Drives

This pack contains twenty new Seagate Cheetah 15K.7 enterprise hard drives, each offering 600GB capacity with a 15000 RPM spindle speed and 16MB cache. The drives use a SAS 6Gb/s interface and a 3.5-inch form factor, supplied as bare units without retail packaging. They are built for high-throughput server and storage arrays that demand sustained random I/O performance.

Suited for Multi-Drive Arrays

Storage architects populating rackmount enclosures or external JBODs with identical spindles will benefit from the matched firmware and consistent 2ms average latency across all twenty units. The quoted 0.55 percent annualized failure rate and 1x10E16 unrecoverable error rate support reliability planning for mission-critical workloads. Buyers who need a single drive or a smaller quantity should look elsewhere.

15000 RPM Spindle Speed

The 15000 RPM rotational speed is the decisive specification that determines whether this drive meets the required random-access latency for transaction-heavy databases or high-frequency logging. Lower-speed alternatives cannot deliver the same IOPS density, while the SAS 6Gb/s interface ensures the full throughput potential reaches the controller.

Questions sur cet article

Will the 15000 RPM spindle motor need scheduled bearing replacement?

The drive carries an annualized failure rate of .55 percent, indicating the spindle assembly is rated for continuous enterprise operation without scheduled bearing service.

What limit appears first when the SAS 6Gb/s link runs sustained writes at 15000 RPM?

The 16MB cache and 2ms average latency bound burst absorption before the 6Gb/s interface saturates during prolonged write streams.

How much heat and noise does a 3.5 inch 15000 RPM drive produce running all day?

Enterprise 15000 RPM 3.5 inch drives typically require forced-air cooling and generate audible seek noise above idle office levels during continuous duty.
