A 1 TB 3.5 inch SATA desktop hard drive spinning at 7.2K RPM for bulk storage

  • 1 TB capacity for desktop storage
  • 2 K RPM spindle speed for responsive access
  • SATA interface for broad motherboard compatibility
  • 5 inch form factor fits standard drive bays
  • New condition with 30 day warranty coverage

Purpose-built 1TB SATA storage

This 1 TB desktop hard drive delivers 7.2 K RPM spindle speed over a standard SATA interface. It fits any 3.5 inch bay and is suited for bulk data, backups or secondary storage in a workstation or home PC.

Steady throughput under load

The 7.2 K RPM mechanism maintains consistent transfer rates during long sequential reads and writes rather than throttling after a short burst. This makes it reliable for extended file copies, video ingest or archive jobs that run for hours.

Verify bay and cable before ordering

Confirm your chassis has a free 3.5 inch drive bay and that your motherboard or controller provides an available SATA data port plus a matching power connector. The drive is not compatible with M.2 slots or PCIe-only backplanes.

Questions about this item

How much noise and heat does the 7.2K rpm 3.5" SATA drive generate when running continuously?

The 7.2K rpm spindle speed and 3.5" form factor produce typical mechanical-drive acoustics and warmth; adequate case airflow keeps temperatures in check during all-day operation.

What must my desktop already have to install this 3.5" SATA hard drive?

A free 3.5" drive bay, a SATA data cable, a SATA power connector from the power supply, and a motherboard SATA port are required for installation.

Will this 1TB SATA drive work alongside the older IDE drives I still use?

Yes — the drive uses the standard SATA interface, so it coexists with legacy IDE devices when the motherboard provides both SATA and IDE connectors or a suitable adapter is used.
