Pros & Cons

Pros

✓ Up to 280MB/s read speeds for fast offloads of 4K footage and large photo sets
✓ Up to 180MB/s write speeds for high-res capture and burst shooting
✓ V60 rating for sustained Full HD and 4K UHD recording without dropped frames
✓ Backed by a 10-year limited warranty from Lexar

Cons

✗ Full 280MB/s needs a UHS-II reader and host; UHS-I slots run at slower speeds
✗ A1 rating, not A2, so random app performance is below A2-class cards
✗ Write speed tops out at 180MB/s, well below the 280MB/s read speed
✗ Priced higher than UHS-I cards, so the premium is wasted in UHS-I-only devices

Manufacturer description

The Lexar 256GB Gold microSD card is a UHS-II microSDXC card for drones, action cameras, and UHS-II handheld gaming devices. Lexar rates it for reads up to 280MB/s and writes up to 180MB/s, which it says makes transfers up to 75% faster than UHS-I cards. That speed matters when you offload a full day of high-resolution photos or 4K clips to your computer. The V60 video speed class means the card can record long stretches of Full HD and 4K UHD video without dropped frames. That is what drone pilots and action-camera users need when a shot can't be repeated. The 180MB/s write speed also helps…

SpecPicks Verdict

SpecPicks scored Lexar 256GB Gold Micro SD Card using a rating × review-volume × price-fit model applied to published specs and reviews across the external storage category. Lexar's external storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for external storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.
