We had only two real complaints about WD's original My Passport Wireless media-streaming Wi-Fi hard drive: short-ish battery life, and an inability to charge other devices. WD has remedied both shortcomings with the all-new My Passport Wireless Pro.

WD's My Passport Wireless Pro is one of the most feature rich storage devices I have seen in a very long time, but it certainly comes at a price.

The My Passport Wireless Pro improves on its previous iteration in some ways and packs more bits than any wireless hard drive to date, but its mixed-bag software and usability hiccups gave us pause.

Integrated SD 3.0 card slot; Available in 2TB or 3TB capacities; Good battery life for a wireless hard drive

Glitchy experiences; even after a WD firmware update; Bulky; non-traditional size; Bumpy software implementation

Western Digital is following up their mobile My Passport Wireless drive with the My Passport Wireless Pro, a lightweight portable drive that is lighter, faster, and available in larger capacities with greater battery life.

Large storage capacity; lightweight and portable; decent battery life; pass-through Wi-Fi; integration with Plex and Adobe CC; user-friendly software

Occasional disconnects during streaming; streaming can lag if more than three or four devices are connected at once; getting it to work well with Plex takes quite a bit of effort and know-how; My Cloud app could use more file organization options; not rugged

Smartphones and tablets have certainly gotten more and more capacious in the last twelve months: Apple's got an iPad with 256GB of space, and SanDisk's 200GB microSD card similarly upped the ante for Android.

OK, you pay a hefty premium to cut the cord and go wireless. A standard 3TB portable hard disk will set you back about £80, but you'll have to splash out £200 for the same storage here.

Built-in Plex for serious streaming; Better battery life than the Energiser bunny; Backup modes keep your files safe

About as exciting to look at as a house brick; Hardly pocket-friendly; is it; Don't drop it on your foot - it's a heavyweight

Broadly speaking, there are two types of people who need a portable hard drive. One type just needs a little additional storage periodically and would rather have something flexible and portable than a big honking drive that plugs into the wall.

The My Cloud app is largely unchanged from the version launched with the original My Passport Wireless. We detailed most of those features All connected media can be accessed from the app - you can browse all files on attached SD cards as well as smartphones connected to the USB 2.0 port.
