SpecPicks Verdict

SpecPicks scored Lexar E-Series 128GB 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. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

How much 4K video fits on one of these 128GB cards?

Lexar rates each 128GB card for up to 6 hours of 4K UHD video, or up to 20 hours of 1080p. Formatting overhead means usable capacity lands below the labeled 128GB.

Is this Lexar card fast enough for 4K recording on a GoPro or drone?

Yes. The card carries V30 and U3 video speed marks, which guarantee a 30MB/s sustained write floor, the threshold most 4K action cameras and drones require.

What exactly comes in the box?

Two Lexar E-Series 128GB microSDXC cards and one SD card adapter. If you need adapters for both cards simultaneously, plan on sourcing a second one.

What is the warranty on the Lexar E-Series microSD card?

Lexar provides a 10-year limited warranty on each card and a one-year limited warranty on the included SD adapter.

Will the 100MB/s read speed hold up on my phone or laptop?

Only if the host supports UHS-I. Lexar measured 100MB/s on its own internal test setup, and devices without UHS-I support fall back to slower legacy interface speeds.

Key Features

(Due to different capacity algorithms and partial capacity are used for system files, management and performance optimization, so the actual available capacity may be less than the identifying capacity.)

10-year limited warranty for card and one-year limited warranty for adapter.
