Pocket-Size Footprint

A drive that rides in a jacket pocket gets carried, while a brick stays home.

Bus-Powered, No Adapter

One cable and no wall brick is the difference on a plane tray table.

Shock-Tolerant Housing

Bags get dropped, and a solid-state design plus a shell handles the knock.

Short or Tethered Cable

The cable is what goes missing, so a captive one saves a whole trip.

Runs Cool Inside a Bag

Packed drives have nowhere to dump heat while a long copy is running.
