Seventh in this guide to 256GB USB flash drives, the Lexar D50E is a dual-connector drive — USB-C and USB-A on the same metal body — listed at £64.99 with 4.6 out of 5 from 328 ratings. Lexar sells it on convenience as much as speed: no cable to lose, a swivel metal housing, and a free app for backing up photos on iOS and Android.

The finding on this listing is that the headline and the specification table finally agree. The title promises "Up to 400MB/s Read" and the spec field says 400 megabytes per second. Two other fields are harder to square. The write speed is listed at 360MB/s, only 40MB/s below the read figure, which is a far narrower gap than flash drives normally show; and the Hardware Interface field reads "USB 2.0, USB 3.2 Gen 1" while a bullet claims transfers "4X faster than USB 3.0". The Best Sellers Rank also files it 14th in External Solid State Drives, not in flash drives. Everything on this page comes from the Amazon listing, not from a test of our own.

## Questions people ask

**Does the Lexar D50E 256GB actually reach the 400MB/s in its headline?**

The title and the specification table agree here: both state 400MB/s read. The same table lists a 360MB/s write speed. We have not tested the drive, so we can only report what the Lexar listing says.

USB-A and USB-C, on a dual-connector body with no cable needed. The listing names iPhone 17, Android and PC as compatible devices.

Lexar states that the free Lexar App Photo Backup function is available for both iOS and Android to back up and manage media.

It reads "USB 2.0, USB 3.2 Gen 1", which sits oddly beside a bullet claiming file transfers 4X faster than USB 3.0.

£64.99 as listed.
