Manufacturer description

The Lexar D40E Dual Drive solves the connector problem that leaves files stranded between your phone and your laptop. One end is USB Type-C, the other is standard USB Type-A, and a 360-degree swivel body switches between them without a cap to lose. Lexar rates transfer speeds at up to 100MB/s over USB 3.2 Gen 1 based on internal testing, so moving a folder of phone video to a Mac or Windows machine doesn't turn into a coffee break. Each drive holds 256GB, and this listing ships two of them. The metal housing keeps the D40E at 26g and 70.4 x 16.9 x 11.7mm, small enough to live on a keyring…
