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.

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.
