Silver 3.5 inch hard drive mounted in a black plastic caddy tray

DELL Constellation ES.3 55FX5 2TB 7200RPM SATA 3.5" internal hard drive with tray

SKU CH-XHW2-2E6SD

A 2 TB 3.5-inch SATA desktop hard drive spinning at 7200 RPM with 128 MB cache and an included R-series tray

  • 2TB capacity stores large datasets and media libraries
  • 7200 RPM spindle speed delivers responsive data access
  • 128 MB cache buffers bursts for smoother throughput
  • SATA 6Gb/s interface connects to standard desktop controllers
  • Includes R-series tray for tool-free 3.5-inch bay installation

Capacity and interface

This is a 2TB 3.5-inch internal hard drive with a SATA 6Gb/s interface spinning at 7200RPM. It ships new with a Dell R-series tray for direct installation in compatible bays. The Seagate-manufactured mechanism provides a 128MB cache buffer.

Suitable use cases

The drive suits desktop workstations and servers that accept 3.5-inch SATA drives and need bulk capacity for archives, backups or secondary storage. It is not for systems that only have 2.5-inch bays or M.2 slots. Buyers who require solid-state speed or silent operation should consider a different technology.

Deciding specification

The 3.5-inch SATA 6Gb/s form factor with included tray determines whether this unit fits the target chassis and backplane. Verify that the host system supports 3.5-inch SATA drives and can accommodate the supplied caddy before purchase.

Questions about this item

Will the included R-series tray fit a standard 3.5-inch drive bay?

The tray is made for LFF 3.5-inch bays and matches the 3.5-inch SATA form factor of the ST2000NM0033 drive.

Which side of the tray should face the backplane when I slide the drive in?

Align the SATA data and power connectors on the drive with the backplane, then push the tray until the latch clicks.

How often should I check the 128MB cache performance as the drive ages?

Monitor SMART attributes such as reallocated sectors and seek error rate; the 7200RPM mechanism is rated for continuous enterprise workloads.
