Overview
Lexar built the D40E with a metal housing and a swivel cover that rotates over the connector instead of a loose cap. Dual connectors let it plug into USB-C phones and tablets as well as laptops and desktop computers.
A swivel design protects the plug in a bag or pocket, and the metal body resists daily knocks. The listing is vague on write speed units, and only the USB-C smartphone class is named as compatible.
Who it's for
A student, traveler or office worker who shuttles documents, photos and video around. The swivel cover suits a bag or keychain. Heavy video editors need a faster drive.
Pros and cons
- Swivel design with no cap to lose
- Works with USB-C smartphones
- Three year warranty
- Write speed lacks a unit
- Only USB-C phones named
- Larger than tiny nano drives
- Connector pair details not listed
Performance notes
Real transfer time depends on the port, since the rated read speed needs a fast USB port on the host. Writing is slower than reading, so copying to the drive takes longer than copying from it. Phones can feed power to the drive but limit sustained speed.
