Manufacturer description
The Lexar Professional 1000x 256GB SDXC card is built for photographers and videographers who fill cards fast and hate waiting on transfers. It uses UHS-II technology at UHS Speed Class 3 (U3) to hit read speeds up to 150MB/s, which is where the 1000x rating comes from. That headroom is what lets you capture 1080p full-HD, 3D, and 4K video on a DSLR, HD camcorder, or 3D camera without the card becoming the bottleneck mid-take. With 256GB of capacity, you can shoot through a long event, a wedding, or a full travel day without swapping cards or triaging footage in the field. The same UHS-II…
SpecPicks Verdict
SpecPicks scored Lexar Professional 1000x 256GB SDXC UHS-II 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
How fast is the Lexar Professional 1000x 256GB card?
It leverages UHS-II technology at UHS Speed Class 3 (U3) for read transfer speeds up to 150MB/s, which is what the 1000x rating refers to. Lexar does not publish a separate sustained write figure for this card, so check the product listing for write specs.
Will this card work in my older camera that isn't UHS-II?
Yes. The card is backwards compatible: it runs at UHS-I speeds in UHS-I devices and at Class 10 speeds in older non-UHS cameras and readers. You just won't see the full 150MB/s until you pair it with UHS-II gear.
Can it handle 4K video recording?
Yes. Lexar rates it for capturing 1080p full-HD, 3D, and 4K video from a DSLR, HD camcorder, or 3D camera. Confirm your specific camera's recommended card class in its manual, since bitrate requirements vary by body.
Is 256GB enough for a full day of shooting?
Lexar positions the large capacity options up to 256GB specifically so you can shoot longer without changing cards, which covers most single-day event, wedding, and travel shoots. Actual clip count depends on your resolution and bitrate.
Does the Lexar Professional 1000x come with a warranty?
Lexar backs the card with a Limited Lifetime warranty and expert support. Check the current product listing for the exact terms and any regional differences before you buy.
