The SanDisk Ultra Dual Drive Go 64 GB is the number one pick in this guide. It is a two-connector drive — reversible USB Type-C at one end, traditional Type-A at the other — listed at £13.79 with 4.5 out of 5 from 51,170 ratings.

On the speed question, this listing is not the copied-and-pasted pair that turns up elsewhere in this guide. The read figure is stated twice and agrees both times: up to 300MB/s in the bullets, 300 Megabytes Per Second in the specification. The write figure is given separately, as 100 MB/s — a third of the read speed, which is the sort of gap a flash drive actually shows rather than the write field being filled in with the read number. Two other entries in the listing are harder to square with the product. The item dimensions read 16 x 10 x 10 centimetres, which would make a swivel drive with a keyring hole 10 cm wide and 10 cm tall, and a Class 10 speed class — an SD card field — appears on a drive that takes no SD card. Everything below comes from the Amazon listing, not from testing we carried out.
