External SSDs

A roomy, fast 10Gbps backup drive that's tethered to the past – and to a power outlet

The SK hynix Tube T31 delivers top "flash drive" speeds by bolting an M.2 SSD onto a USB-A port. It's one of the fastest drives you can buy without having to fuss with a cable.

Impressive for the price, as long as you don't count sustained write speeds

Great peak performance for a 10Gbps drive, plus good sustained writes at a nice price.

Fast 20 Gb/s performance, for as long as the cache lasts

Roomier and faster than a portable HDD, but the street price needs to be much lower than MSRP.
