Capacity and purpose

The Western Digital WD20EZRX is a 2TB 3.5" desktop hard drive built for low-power storage in PCs or external enclosures. It suits users who prioritise quiet, cool operation over maximum throughput.

Build and connectors

The bare drive uses a standard SATA 6.0Gb/s interface and a 64MB cache to handle everyday file storage. Its IntelliPower spindle speed and 1.0-inch low-profile height keep heat and noise low in typical desktop chassis.

Interface limits

The SATA 6.0Gb/s link caps peak transfer rates well below modern solid-state alternatives. Buyers needing faster boot or application loads should consider a different storage technology.

Questions about this item

What does the SATA 6.0Gb/s interface cap the WD20EZRX at in practice?

The SATA 6.0Gb/s interface caps the drive at 6.0Gb/s, though the 5400 RPM IntelliPower spindle and 64MB cache typically limit sustained throughput to well below that ceiling.

What physical space and mounting does the 3.5-inch WD20EZRX need?

It requires a standard 3.5-inch drive bay with 1.0-inch low-profile height clearance and four side or bottom mounting holes on 3.5-inch centres.

How is the WD20EZRX installed, and what step do people often miss?

Connect a SATA data cable to the motherboard and a SATA power connector from the PSU, secure the drive with screws, then initialise and format the 2TB volume in the OS — the step many skip.
