Manufacturer description
The Lexar Professional 2000x 128GB SDXC card is built for photographers and videographers who shoot faster than their storage can keep up. It leverages UHS-II technology with a UHS Speed Class 3 (U3) rating to deliver read transfer speeds up to 2000x, or 300MB/s, so you can fill a buffer with continuous RAW bursts and clear it quickly instead of watching a write indicator. The 128GB capacity handles extended sessions of 1080p Full-HD, 3D, and 4K video from a DSLR, HD camcorder, or 3D camera without a mid-shoot card swap. What sets this Lexar SDXC card apart from the card alone is the bundled…
SpecPicks Verdict
SpecPicks scored Lexar Professional 2000x 128GB SDXC UHS-II 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. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
Is this card fast enough for 4K video?
Yes. It carries a UHS Speed Class 3 (U3) rating, the class defined for sustained 4K capture, and Lexar lists 1080p Full-HD, 3D, and 4K video as supported use cases.
What is the actual read speed of the 2000x rating?
2000x converts to a read transfer speed of up to 300MB/s over UHS-II. Write speed is not listed in the product specifications, so check the Lexar listing for the rated write figure.
Does it work in a camera that only supports UHS-I?
Yes, the card is backwards compatible with UHS-I devices. You will get UHS-I speeds in that body, not the full 300MB/s, since UHS-II uses a second row of contact pins.
Does the card come with a reader?
Yes. An SD UHS-II reader is included, which is what lets you hit high-speed card-to-computer transfer instead of bottlenecking at a UHS-I slot during offload.
What warranty coverage does Lexar provide?
Lexar provides limited lifetime product support on the card itself and 1-year limited support on the included reader. Check the product listing for current terms in your region.
