Deskstar 7K1000.C 320GB SATA drive

The HGST Deskstar 7K1000.C is a 3.5 inch internal hard drive with a 320GB capacity. It spins at 7200 RPM and includes a 16MB cache on a SATA 3.0Gb/s interface. The bare drive uses a halogen-free design and suits desktop storage upgrades.

Ideal for basic desktop storage needs

This drive fits users who need affordable extra space for documents, backups or a secondary operating system. It is not for builders who want faster application loading or quieter operation than a mechanical disk can give. Buyers who need more capacity or solid-state speed should look at other options.

320GB capacity with 7200 RPM performance

The 320GB platter handles everyday file storage and operating system duties without difficulty. Large media libraries, modern game installs or heavy video editing projects will exceed the available space quickly. The 16MB cache helps burst transfers but sustained throughput is limited by the SATA 3.0Gb/s link and rotational latency.
