  • Oodles of storage, attractive design, included security software


  • It's expensive, you'll probably lose the lid

Bottom Line

The Kingston DataTraveler 310 is currently the highest capacity USB flash drive on the market: its almost like having an external HDD in your pocket. Unfortunately, you have to pay a fair whack for the privilege. Nonetheless, if you require lots of storage on-the-go, this is the thumb drive to get.

Would you buy this?

The Kingston DataTraveler 310 is a USB 2.0 flash drive with a gargantuan 256GB of storage. This is the highest capacity currently available on the market; putting it in the same league as some entry-level external hard drives. (Not bad for a device that’s smaller than a tube of lipstick.)

The Kingston DataTraveller 310 also comes equipped with PasswordTraveler; a security application that protects important files in a secure zone. On the downside, it definitely isn’t a cheap device; with an RRP of $1299. Data transfer speeds are also a bit sluggish — especially compared to ‘proper’ external hard drives, such as the Western Digital My Passport Studio and the LaCie Rikki. Nonetheless, if you require lots of storage in an ultra-portable format, the Kingston DataTraveler 310 is incredibly hard to beat.

The Kingston DataTraveler 310 is fairly bulky for a USB thumb drive; with dimensions of 73.70x22.2x16.1mm (hey, all that memory has to fit somewhere!) That said, it is still small enough to slip inside your purse or jean pocket, so the extra millimetres aren’t that big of a deal. The casing is both attractive and durable: we particularly liked the metallic red finish, which is a nice change from the typical shades of silver.

Unfortunately, Kingston has opted for a traditional lid for the DataTraveler 310 (as opposed to the swivelling variety found on competing thumb drives like the Lexar 360 range). Consequently, losing the lid forever is a distinct possibility.

To test the Kingston DataTraveler 310’s file transfer speeds, we copied two folders onto the drive and then back onto the desktop. We also copied the folders from one location on the drive to another to test its speed when simultaneously reading and writing files. Each test folder contained a variety of files adding up to 3GB and 19.2GB, respectively. In the table below, we compare the results to some of the external hard drives currently on the market. [Note: the DataTraveler 310 is a thumb drive, so a slower performance is to be expected.]

As you can see, the Kingston DataTraveler 310 cannot hope to compete with an external HDD, but it still gave a pretty good performance for a USB thumb drive.

Despite being tagged with the ‘DataTraveler’ moniker, the 310 is equally suited to use in the home. Its small size and massive capacity make it an ideal accompaniment to a USB media streamer, such as the Western Digital WDTV or Sony SMPU10.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

As a freelance writer who is always on the go, I like my technology to be both efficient and effective so I can do my job well. The HP OfficeJet Pro 8730 Inkjet Printer ticks all the boxes in terms of form factor, performance and user interface.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
