Overview

WD Green drives were designed for desktops where low power draw matters more than raw speed. The WD40EZRX is a 4TB 3.5in LFF model that uses IntelliPower rather than a fixed RPM rating, with a 64MB cache and a maximum transfer rate of 150 MB/s on SATA 6Gb/s.

Its power figures show the focus: 5.3 W in read/write, 3.4 W at idle and 0.4 W in standby. That makes it a good fit for a secondary data drive in an office desktop, a media library or an always-on home-office PC.

The drive is rated for 300,000 load/unload cycles, operates from 0 to 60°C and weighs 0.68 kg.

As the WD Green line is no longer current, buyers usually want this exact MPN to match existing machines. The WD40EZRX is available New or Refurbished, with 1 year or 3 years of warranty for either. Add your quantity to the request for a reply with pricing.
