500 GB 2.5-inch SATA desktop drive

The Western Digital WD5000BPKX-50PK is a 500 GB internal hard drive built for 2.5-inch SATA drive bays in desktop systems. It spins at 7.2 K RPM with a 16 MB cache and uses a SATA 6 Gb/s interface. The unit is supplied new from undeployed systems without original retail packaging.

Fits SATA 2.5-inch bays.

This drive suits desktops and workstations that accept a 2.5-inch SATA device and need 500 GB of mechanical storage. Builders whose cases or drive cages only provide 3.5-inch mounting space cannot install it without an adapter. Systems requiring solid-state speed or higher capacities should consider other options.

7.2 K RPM spindle speed

The 7.2 K RPM rotation rate determines the drive's sustained transfer performance and access latency for typical desktop workloads. Verify that the host system's SATA controller and power delivery support a 2.5-inch mechanical drive before purchase.

Questions about this item

How much power and heat does the 7.2K 500GB SATA drive produce when running continuously?

The 7.2K spindle speed and 500GB capacity draw modest power for a 2.5in SATA drive, so heat output stays low during all-day operation.

What must my system provide for this 2.5in 500GB SATA drive to work?

A free 2.5in drive bay or bracket, a standard SATA data cable, and a SATA power connector from the power supply.

Will this 500GB 7.2K SATA drive work alongside an older 3.5in SATA drive in the same machine?

Yes — both use the same SATA interface, so the 2.5in 500GB drive and an older 3.5in SATA drive can share the same controller without conflict.
