10 best external hard drives

After some additional storage space? We've found the best kit to grow your computer's capabilities

From portable to desktop, our top picks delivers a wide range of storage solutions ( iStock )

With most of us relying on compact mobile devices of various sorts for our day to day computing, gone are the days of upgrading your storage by popping another hard drive in your PC. Nowadays, the easiest option is to buy an external drive, but with so many to choose from, it can be difficult to know which best suits your purposes. 

Large desktop-bound hard drives can provide loads of storage for a low price, while smaller, portable options let you bring your extra storage with you. SSD-based drives provide lightning quick performance that are ideal for working directly from, while mobile-phone compatible thumb drives make it easy to quickly clear a bit of space so you can keep snapping photos and recording your memories. 

A network-accessible NAS drive is also useful for sharing data all round your house or office. Whichever sort of drive you need, we’ve picked out the best ones on the market.

Seagate Expansion+ Portable Hard Drive, 1TB: £44.99, Argos

External hard drives don’t have to be clever or complicated and the Seagate Expansion+ is neither of those things. Plug this drive into your computer’s USB port and you have instant access to an extra 1TB (or up to 4TB) of storage. It’s also small enough to fit in your laptop bag and stylish enough that it won’t look out of place in a swanky office. It’s not particularly fast and you get few extras to speak of, but it’s hard to argue with such a reasonable price.

Samsung T5 Portable SSD, 500GB: £120, Currys

The Samsung T5 Portable SSD provides a perfect balance of portability, performance and price.

It connects via USB 3.1 Type C – that’s the one with the reversible plug – so is convenient as well as quick. It’s pricier than a portable hard drive, but if you need a bit of extra performance and a more portable package, it’s a great option.
