Manufacturer description
The Lexar E-Series 512GB microSDXC card is a straightforward capacity upgrade for phones, tablets, drones, GoPro and other action cameras. Lexar rates it at up to 100MB/s read over the UHS-I bus, and the card carries the C10, U3, A1 and V30 marks - the V30 rating is the one that matters if you are recording 4K UHD or 1080p Full HD footage, since it signals sustained write headroom rather than a burst peak. At 512GB, Lexar says the card holds roughly 24 hours of 4K video, 75 hours of 1080p, about 150,300 photos or 77,330 songs, though formatting and system files mean usable space lands below…
SpecPicks Verdict
SpecPicks scored Lexar E-Series 512GB Micro SD Card using a rating × review-volume × price-fit model applied to published specs and reviews across the PC & gaming hardware category. Lexar's PC & gaming hardware 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 PC & gaming hardware 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.

Frequently Asked Questions
Is this microSD card fast enough for 4K video?
Yes. The card carries V30 and U3 ratings, which Lexar lists specifically for 1080p Full HD, 3D and 4K UHD capture and playback. Lexar states 512GB holds up to 24 hours of 4K video.
Does it come with an SD adapter?
Yes, a full-size SD adapter is included. Note the adapter carries a 1-year limited warranty while the card itself has a 10-year limited warranty.
How much can a 512GB card actually store?
Lexar rates it at up to 24 hours of 4K video, 75 hours of 1080p video, 150,300 photos or 77,330 songs. Actual free space is lower than 512GB because of formatting and system files.
Will this work in my GoPro or drone?
Lexar lists smartphones, tablets, drones, action cameras and GoPro as intended devices. Check your camera's manual for its maximum supported capacity before buying the 512GB version.
Is the 100MB/s speed guaranteed?
No. Lexar measures up to 100MB/s in its own internal test environment over UHS-I, and states real speed varies by host device. Devices without UHS-I support will run slower.
