SKU CH-HDDD-XNJ4A

A 1 TB, 7200 RPM, 2.5 inch SATA desktop hard drive with 64 MB cache and hot-swap support

  • 1TB capacity stores large files and applications
  • 7200RPM rotation speed delivers fast data access
  • 5 inch SATA form factor fits compact desktop bays
  • 64MB cache improves read and write performance
  • Hot-swap support allows drive replacement without shutdown

Purpose and fit

The Dell Constellation.2 is a 1TB 2.5 inch SATA hard drive spinning at 7200RPM with 64MB cache. It suits desktop builders who need a hot-swappable mechanical drive for bulk storage in a compact bay.

SATA interface limits

The SATA connection caps sustained throughput well below modern solid-state speeds, so large file copies and boot times remain constrained by the mechanical platter. Random access latency is inherent to the rotating design and cannot be overcome by the interface.

Deciding specification

The 2.5 inch form factor combined with hot-swap support determines whether the drive fits your chassis and backplane; systems limited to 3.5 inch bays or without hot-swap cages cannot use this unit.
