HGST HCS721050CLA362 500GB 7200RPM 16MB 3.5" SATA internal hard drive

Capacity and fit

This is a 3.5 inch internal hard drive with 500GB capacity for desktop computers. The 7200RPM spindle speed and 16MB buffer suit general storage and operating system duties. It is a new drive from HGST, sold under the Hitachi model HCS721050CLA362.

SATA 3Gb/s interface

The single specification that decides compatibility is the SATA 3Gb/s interface on a 3.5 inch form factor. Your motherboard or controller must provide a matching SATA port and the chassis must accept a standard 3.5 inch drive bay.

Sustained workload behaviour

Under continuous use the 7200RPM rotation delivers steady sequential throughput limited by the 3Gb/s link and 16MB cache. Mechanical latency and heat output remain constant during long transfers, unlike burst-oriented solid state alternatives.
