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.

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.

External storage is commonplace now, but traditional standalone storage products sometimes leave a large number of devices hanging. I've got a 2TB external drive plugged into a USB 3 port, for example, which is great for the main PC, but it doesn't help much with the laptop, iPhone and iPad.

To see how much data throughput I was able to pull from a WiFi connection to the Western Digital My Passport Wireless Pro 2TB, I used a 2015 13" Apple MacBook Pro equipped with a Broadcom 802.11ac wireless adapter. This MacBook Pro is considered one of the best laptops in the market at press time.

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.

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

This device is great for my photography workflow. It's powered so you can just back-up your SD cards in the field using the in-built card reader (USB 3.0 so this is a fairly quick process).

I bought this as a memory card backup device for a trip to the Galapagos. It worked fine at home. But when I got to Ecuador, the Wireless Pro stopped any detectable wireless communication. I tried backing up my SD cards, but could not see if they had been copied to the hard drive.

The My cloud app for android automatically backs up pictures and videos. If you wish to back up other files such as music, documents, or SMS text messages, then you must use another app or complete the task manually.

I loved the concept but it was difficult to set up and use, After several firmware updates, it dies while travelling in India. Replaced under warrantywhen I returned. I had to send in the dead drive with all my data on it to get it replaced. A few months later the new unit died. Not a happy camper

Used this on recent trip, and was delighted. I usually carry a laptop and portable drive to back up memory cards when traveling. With a short trip, decided to take this and leave laptop home. Straightforward function to insert SD card, it makes copy in new folder with the date.
