Bottom line: The WD 4TB White-Gold My Passport Ultra Portable External Hard Drive: 4TB capacity in a bus-powered pocket-size enclosure, no external power brick; main trade-off: spinning hard drive, so far slower than an SSD of the same price.

Manufacturer description

The WD My Passport Ultra 4TB portable external hard drive gives you 4TB of pocketable storage behind a metal-and-matte finish that reads more like a piece of hardware than a plastic backup box. It connects over USB 3.0 and stays backward compatible with USB 2.0, so it works with older laptops and desktops you haven't retired yet. Western Digital bundles WD Discovery, which handles social media and cloud storage import, scheduled WD Backup jobs, and password protection so the files you drag onto the drive aren't readable by anyone who picks it up. Setup is plug-and-go: connect the bus-powered…

SpecPicks Verdict

SpecPicks scored WD 4TB White-Gold My Passport Ultra Portable External Hard Drive using a rating × review-volume × price-fit model applied to published specs and reviews across the external storage category. Western Digital's external storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for external storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.
