500 GB 2.5" 7200 RPM SATA drive

This HP internal hard drive delivers 500 GB of storage in a 2.5 inch form factor spinning at 7200 RPM over a SATA interface. It is supplied new and carries part numbers 655708-B21, 656107-001 and 614829-002. The drive fits standard laptop or small-form-factor desktop bays.

Suits storage upgrades in compatible bays

The drive suits users adding primary or secondary storage to systems with a 2.5 inch SATA bay. Builders whose chassis only accepts 3.5 inch drives or who require a different interface cannot use this unit. Buyers needing capacities beyond 500 GB must select another model.

7200 RPM rotational speed

The 7200 RPM spindle speed determines the drive's sustained transfer rate and access latency. This single specification decides whether the performance profile matches the workload. Verify that the host system supports 2.5 inch SATA drives before purchase.

Questions about this item

How much heat and noise does the 7200RPM 2.5" SATA drive produce when running continuously?

The 7200RPM spindle generates moderate heat and audible seek noise typical of a 2.5" mechanical drive; ensure your chassis has airflow over the drive bay.

What host connector and bay size does the 655708-B21 need to work in my system?

It requires a standard SATA data and power connector plus a 2.5" drive bay or a 3.5" adapter bracket.

Will this 6G SATA 500GB drive work alongside an older 3G SATA controller in my desktop?

Yes, the SATA interface is backward compatible, so the drive will negotiate 3G speeds on an older controller.
