USB flash drives

A USB flash drive is for moving files between devices, not for keeping a lasting backup. The connector comes first: a standard plug, the reversible type found on recent phones, or both. Between two similar-looking models, write speed varies enormously and changes how long copies take. A capless casing that clips onto a keyring prevents many losses.
