RE3 enterprise drive for desktop

The Western Digital RE3 WD5002ABYS is a 3.5-inch internal hard drive built for desktop workloads. It offers 500GB of capacity on a SATA 3.0Gb/s interface with a 7200 RPM spindle speed and 16MB cache. The drive arrives as a bare unit, erased to DoD 5220.22 M standard and tested for working condition. It is sold new without formatting or partitioning applied.

Suits RAID and archive duties

This drive suits builders adding bulk storage to a desktop, a home server or a RAID array where 7200 RPM throughput matters. The 16MB cache and 4.2ms average latency support steady sequential workloads. Buyers who need a boot drive with faster random access or who require a larger single volume should look at something else. The bare-drive packaging means no cables or mounting screws are included.

SATA 3.0Gb/s interface decides fit

The single specification that decides compatibility is the SATA 3.0Gb/s interface. Your motherboard or controller must provide a standard SATA port running at 3.0Gb/s or higher to use this drive. A 3.5-inch drive bay and a SATA power connector are also required. Verify these connections before purchase.

Questions about this item

How much power and heat does the WD5002ABYS produce when running continuously?

The 7200 RPM spindle and 16 MB cache draw typical desktop 3.5" drive power; expect normal operating warmth and audible seek noise during sustained use.

What existing hardware is required to install this SATA 3.0Gb/s drive?

You need a free SATA data port on the motherboard or controller, a matching SATA power connector from the PSU, and a 3.5" drive bay or mounting bracket.

Will the WD5002ABYS work alongside an older IDE drive in the same system?

Yes, the SATA interface operates independently of legacy IDE channels; both drives can coexist if the board provides both connector types.
