2TB Desktop Storage for Everyday Computing

The Western Digital WD20EZBX is a 3.5 inch internal hard drive built for desktop PCs that need reliable capacity for office tasks, web browsing and general file storage. It spins at 7200 RPM with a 256MB cache and connects through a SATA 6.0Gb/s interface. Buyers who need faster boot times or heavy multi-tasking performance should consider solid-state alternatives.

Low Power Consumption and Quiet Operation

Advanced seeking algorithms and power management keep electricity draw low during normal desktop use. NoTouch Ramp Load technology prevents the recording head from contacting the disk surface, reducing wear and protecting data during transport. The drive fits standard 3.5 inch bays with maximum dimensions of 147.00mm length, 101.60mm width and 26.10mm height.

Acronis Cloning Software Simplifies Migration

A free download of Acronis True Image WD Edition lets you clone an existing drive to this new unit without reinstalling the operating system or applications. The utility handles the transfer automatically, so the upgrade finishes in a single session. Western Digital tests each model in its FIT Lab across hundreds of platforms to verify broad system compatibility.

Questions about this item

How do I install the WD20EZBX 3.5" drive in my desktop, and what step is often missed?

Mount the drive in a 3.5" bay using four screws, connect the SATA data cable to a 6.0Gb/s port and the SATA power cable, then initialise and format the 2TB volume in Disk Management — the step most people skip.

What maintenance or replacement will the WD20EZBX need over time?

No scheduled maintenance is required; the 7200 RPM motor and NoTouch Ramp Load head design run without user service. Replace the drive only if SMART attributes report reallocated sectors or if the 256MB cache can no longer buffer writes reliably.

What limit appears first during sustained writes on the WD20EZBX?

The SATA 6.0Gb/s interface caps sustained throughput, so long sequential transfers will hit the bus ceiling before the 7200 RPM platters or 256MB cache become the bottleneck.
