Rank #7 in Best 256GB USB Flash Drives 2026: 10 Ranked by Their Own Spec Tables
Lexar D50E 256GB USB-C + USB-A Dual Drive
Price and rating as shown on Amazon when we collected them. Both change.
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.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Really liked this - spent three days trying to download my life photos on three 1tb sticks which were copying at about 300kb. I never considered speed just capacity... these I was getting 3 to 12mb being copied per sec. I know you can get faster but for price and speed I loved this. Feels robust and allows usb or usb c connection great as new computer only has usb c. Minor negative - no ring included ? No issue just thought it wold come with one. Also design means one connection always exposed. Very robust so wouldn't expect problem but simple rubber or plastic cover for usb end might have been an idea ( just a suggestion. ) overall very impressed and I've now bought 6 moving everything over a lot faster.”
Verified purchase“Always dubious about speed claims on USB memory sticks. But this thing really does deliver. Pushing a 100GB test file to the drive didn't make it sweat. It sustained speed from start to finish (most USB drives start well then speed bombs after a few seconds).4K random read/write is around 1500 IOPS, which is genuinely impressive for a USB stick.As an added bonus, it's gorgeous, and feels durable.”
