Name: Lexar Professional 1000X 128GB (2-Pack) SDXC Uhs-II Cards
Brand: Lexar
SKU: B00SANIGF0

Bottom line: The Lexar Professional 1000X 128GB SDXC Uhs-II Cards: UHS-II U3 read speeds up to 150MB/s (1000x) cut card-to-computer offload time; main trade-off: full 150MB/s speed needs a UHS-II reader and camera; older gear drops to Class 10.

Pros & Cons

Pros

✓ UHS-II U3 read speeds up to 150MB/s (1000x) cut card-to-computer offload time
✓ Two 128GB cards in one box: 256GB total, spare or dual-body ready
✓ Rated U3, the class needed for sustained 4K and 1080p full HD video capture
✓ Backward compatible: UHS-I speeds in UHS-I gear, Class 10 in non-UHS cameras
✓ Includes downloadable Image Rescue software for most photo and select video recovery

Cons

✗ Full 150MB/s speed needs a UHS-II reader and camera; older gear drops to Class 10
✗ 150MB/s is the read figure - Lexar does not state a sustained write speed here
✗ 128GB per card, not a single 256GB volume, so long 4K takes still require a swap
✗ Premium pricing versus UHS-I cards of the same 128GB capacity

Manufacturer description

The Lexar Professional 1000x 128GB SDXC UHS-II card ships here as a 2-pack, aimed at photographers and videographers who fill cards fast and hate swapping mid-shoot. Each card uses UHS-II technology at UHS Speed Class 3 (U3) for read transfer speeds up to 150MB/s (1000x), which is what makes offloading a full 128GB shoot to your computer a coffee-break job rather than an afternoon one. In-camera, that headroom supports 1080p full HD, 3D, and 4K video capture along with burst stills on a DSLR, HD camcorder, or 3D camera. The 128GB capacity per card means you can shoot longer between swaps…

SpecPicks Verdict

SpecPicks scored Lexar Professional 1000X 128GB SDXC Uhs-II Cards 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

How fast are these Lexar 1000x cards?

They leverage UHS-II technology at UHS Speed Class 3 (U3) for read transfer speeds up to 1000x, or 150MB/s. Lexar does not publish a separate sustained write figure for this pack.

Will these work in a camera that isn't UHS-II?

Yes. The cards operate in UHS-I devices at UHS-I speeds and are backward compatible with older cameras and readers, performing at Class 10 speeds when used with non-UHS devices.

Can these handle 4K video recording?

Lexar rates them for 1080p full HD, 3D, and 4K video with a DSLR, HD camcorder, or 3D camera. The UHS Speed Class 3 (U3) rating is the class cameras typically require for 4K capture.

How much storage do you get in this pack?

Two 128GB SDXC cards, so 256GB total across the pair. They are separate cards, not a single pooled volume, so each holds 128GB.

What if I accidentally delete or format a shoot?

The cards include downloadable Image Rescue software, which Lexar states recovers most photo and select video files. Check the product listing for current warranty terms.
