DELL 4TB 7.2K SATA 6GB 9PR63 ST4000NM0033 internal hard drive

SKU CH-NKT2-KA7QM

A 4TB SATA hard drive spinning at 7.2K RPM with a 6Gb/s interface for desktop storage

  • 4 TB storage capacity for large data sets
  • 2K RPM spindle speed for responsive throughput
  • SATA 6 Gb/s interface for broad compatibility
  • OEM packaging ready for server deployment

Capacity and interface

This is a 4TB desktop internal hard drive from Dell that operates at 7.2K RPM over a SATA 6GB connection. It uses the 9PR63 series design identified by part number ST4000NM0033 and arrives in new condition with retail or OEM packing.

Suited for bulk storage, not high-speed tiers

The drive suits users who need large-capacity mechanical storage for archives, backups or secondary data on a SATA platform. Buyers who require faster random-access performance or a different interface protocol should look at other drive types.

Questions about this item

Will the 7.2K RPM spindle speed limit sustained write throughput on this DELL 9PR63 drive?

The 7.2K RPM spindle sets the mechanical ceiling for sequential transfers, so sustained write rates will top out at the speed that rotation allows.

How much heat does the ST4000NM0033 produce during all-day operation?

A 7.2K RPM SATA drive of this capacity typically idles around 33 watts and rises under load, so plan for steady warm airflow in the chassis.
