Dinky, cheap and available in red as well as black (that’s what the ‘R’ stands for), the Kingston XS1000R is a pretty standard external SSD that’ll suit budget-conscious users who don’t need more than 2TB of storage. It’s a no-frills offering, with no included backup software or anything like that, but it'll get the job done without taking up too much room, and its transfer speeds are consistently decent.

Capacity: 1TB-5TB

Want a device that'll withstand hostile conditions? The ADATA HD710 Pro offers three layers of anti-shock technology and can take drops of up to 1.5m.

For a backup solution that you can set up and forget about, the Seagate Backup Plus is just the ticket. With its own backup software you can easily set up to safely store data from all your devices.

Storage options go up to 5TB, giving you plenty of space for data should you need it.

The Samsung T5 is an older model to the T7 Touch, and offers transfer speeds around half as fast; it also lacks the fingerprint scanner. But for a great price, you do get the same high-quality build and reliability, AES 256-bit encryption, and password protection as the T7 Touch. Plus, the T5 is even smaller and lighter (‎at 5.7 x 1 x 7.4 cm and 51g), so if space is valuable to you, this device may be worth considering, and as it's an old model you may be able to pick one up quite cheaply.

Capacity: 256GB, 512GB or 1TB

In general, SSDs can take more punishment than hard drives because they lack the moving parts that are usually the weak spots in HDDs: But the Adata SD700 goes further: it's water-resistant for up to 30 minutes, and is IP68 rated, meaning it can withstand dust, dirt and sand. The starting capacity isn't huge, and the write speeds aren't as fast as the Samsung SSDs on our list, but overall, this is a great option.

There are two additional USB ports, plus 256-bit AES hardware encryption and automatic backup software.
