3TB SATA desktop drive

The Western Digital WD30EZRX is a 3TB 3.5" internal hard drive with a SATA 6.0Gb/s interface and 64MB cache. It uses IntelliPower spindle speed for cool, quiet operation and reduced power consumption. The drive suits daily computing workloads in standard desktop bays.

Upgrade from smaller mechanical disks

Replacing a lower-capacity 3.5" SATA drive with this 3TB model adds substantial space without changing cables or mounting points. The jump is worthwhile when existing storage is full and the system only supports SATA interfaces. It does not suit builders who need faster access times or solid-state responsiveness.

3TB capacity for bulk data

The 3TB capacity comfortably holds large media libraries, backups and archival files. Sequential throughput is limited by the SATA 6.0Gb/s link and mechanical latency, so random I/O heavy tasks such as database work or OS boot will run out of headroom quickly. Drives may show up to 25 bad sectors and carry DoD 5220.22 M erase verification.

FeaturesThe advantage of cool & quiet
Heat has a large impact on the overall reliability of a HDD's life over time. It can also lead to increased power consumption, the requirement of additional fans and increased fan operation, increased noise levels and the increased chance of failure. WD Green drives come equipped with WD GreenPower Technology which allows the drive to operate cooler with increased overall reliability.

Questions about this item

What are the exact dimensions of the 3.5" WD30EZRX so I can confirm it fits my drive bay?

The drive measures 26.10 mm in height, 101.60 mm in width and 147.00 mm in length, matching the standard 3.5" form factor.

Which cables and jumpers are required to install the SATA 6.0Gb/s WD30EZRX, and what is the common mistake?

Connect a standard SATA data cable and a SATA power connector; no jumpers are needed. The frequent error is forgetting to seat the data cable firmly on both the drive and motherboard.

How often should I check the WD30EZRX for bad sectors after the DoD 5220.22 M erase?

Run a full surface scan once after installation to verify the media, then schedule a check every six months; the drive may contain up to 25 bad sectors from prior use.
