However, it should work with any phone or tablet with a microUSB and OTG (on-the-go) support. Also see: Best portable hard drives. 

Freecom Tablet Mini SSD 128GB review: Price

There’s just one capacity: 128GB. It’s expensive at 75p per gigabyte, although that’s the price you’ll pay if you buy the drive direct from Freecom’s website. If you hunt around, you can find it under £70, which takes the price per GB down to 54p. That’s still a bit pricey, though. You can buy it directly from Freecom for £89.

Freecom Tablet Mini SSD 128GB review: Design

Measuring 58 x 92 x 15mm and weighing just 60g, the Tablet Mini SSD is a drive you can carry everywhere without even noticing it. It’s unassuming, finished in demure grey plastic, but it has built-in microUSB and full size USB 3.0 cables, which is very convenient.

The cables slot into the side of the drive so are extremely short which can make it a little awkward at times, especially as it can end up dangling off the side of a tablet, depending on the location of its USB port.

You can’t connect two devices at once: the idea of the two cables is to make the drive compatible with just about every device so you can quickly transfer photos, videos and other media to and from your phone and tablet. Whether you use it for backing up your camera roll or as additional storage for films and music is up to you.  Inside is 128GB of NAND flash, although Freecom doesn’t specify which type. It’s most likely to be TLC. Also see: Best NAS drives.

Bundled with it is Nero BackItUp, Hard Drive Eraser and Formatter. This means you can erase the drive if you ever give it away or sell it on. Nero is a somewhat odd choice as it allows you to make a full system backup (of a Windows PC) but you’re unlikely to do that on a pricey mobile SSD. 

Freecom Tablet Mini SSD 128GB review: Performance 

It may not be the cheapest, but performance is very good. Over USB 3.0, we saw 410MB/s in the CrystalDiskMark sequential read test. Writing wasn’t as impressive at 178MB/s, but it’s still one of the faster drives you can buy. Also see: How to build a PC. For 4KB files – the sort of sizes you find when you’re dealing with anything other than media files – performance was also sterling. The Tablet Mini SSD read them at almost 17MB/s and wrote them almost as quick – 16.1MB/s. Virtually every other portable drive we’ve tested struggles here, managing only a few MB/s.
