500 GB SATA server drive

The HP 658071-B21 is a 3.5-inch internal hard drive built for server and storage environments. It delivers 500 GB of capacity on a SATA 6.0 Gb/s interface. The drive spins at 7200 RPM with a 16 MB cache. It is supplied as a bare drive without a tray or cables.

Smart Carrier tray included

The unit ships with an HP Smart Carrier tray for tool-less installation in compatible bays. This tray adds hot-plug capability where the chassis supports it. No additional mounting hardware or software utilities are bundled. The bare-drive packaging keeps the focus on the drive itself.

Entry workload capacity and limits

The 500 GB volume suits operating-system boots, logging and light application data in entry-level servers. Sequential throughput reaches the SATA 6.0 Gb/s link speed for large-file transfers. Random I/O is constrained by the 7200 RPM spindle and 16 MB cache. Heavy database or virtualization workloads will exceed the drive's practical IOPS headroom.

Questions about this item

Will the 16 MB cache need any maintenance or replacement later?

The 16 MB cache is built into the drive's controller board and is not a separate replaceable part. No maintenance is required for it during the drive's service life.

What limit appears first when the 7200 RPM drive runs under sustained load?

The mechanical 7200 RPM spindle speed sets the maximum sustained throughput. The SATA 6.0 Gb/s interface provides headroom above that mechanical limit.

How much noise, heat or power does the 3.5" SATA drive produce when running all day?

As a standard 3.5" 7200 RPM hard drive it generates typical mechanical noise, moderate heat and draws standard SATA power levels during continuous operation.
