Manufacturer description

Lexar's 64GB microSDXC 2-pack gives you two cards plus a full-size SD adapter, which is the practical reason most buyers pick it over a single-card listing: one card lives in your phone or drone while the other stays free for overflow. Each Lexar 64GB micro SD card is rated up to 100MB/s read, with UHS-I, U3, Class 10 and V30 marks that cover 4K and 1080p video capture without dropped frames on supported hosts. The A1 rating means 1,500 read IOPS and 500 write IOPS, so apps you offload from internal storage launch and respond rather than stutter. Capacity translates to roughly 3 hours of 4K…

SpecPicks Verdict

SpecPicks scored Lexar 64GB Micro SD Card 2 Pack 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

How much video can a 64GB Lexar card actually hold?

Lexar rates each 64GB card at up to 3 hours of 4K video or up to 10 hours of 1080p, plus alternatives like 18,800 photos or 9,900 songs. Usable capacity is slightly under 64GB because system files and management data take a share.

Is this fast enough for 4K drone and action-camera recording?

Yes. The cards carry V30 (Video Speed Class 30) and U3 marks, which are the ratings 4K and Full HD recording modes look for, and read speed runs up to 100MB/s on UHS-I hosts.

Can I use it to run apps on an Android phone?

That is what the A1 rating covers: 1,500 continuous read IOPS and 500 write IOPS, enough to run apps from the card and free up internal phone or tablet storage.

Will it survive water, drops, and airport scanners?

Lexar rates the cards waterproof for 30 minutes at up to 1 meter, shockproof to 500G acceleration, X-ray radiation proof, and anti-static. Operating range is 0 to 70 C, storage range -25 to 85 C.

Does the pack work in a regular SD card slot?

Yes. The pack includes one full-size SD adapter, so either microSD card fits a laptop, camera, or card-reader SD slot. Check the product listing for current warranty terms.
