Manufacturer description
Lexar's Professional 1667x 64GB SDXC card is built for photographers and videographers who shoot 4K and full-HD footage and cannot afford a buffer stall mid-take. The UHS-II interface (UHS Speed Class 3, V60) delivers read speeds up to 250MB/s and write speeds up to 120MB/s, so long 1080p, 3D, and 4K clips record continuously and offload from card to computer fast enough to keep an editing session moving instead of waiting on a copy bar. At 64GB, this Lexar SD card holds a full shoot without a swap in most DSLR and mirrorless bodies, and the same line scales to 256GB if you need more runway…
SpecPicks Verdict
SpecPicks scored Lexar 64GB Professional 1667x SD 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
Is this SD card fast enough for 4K video?
Yes. It is rated V60 with write speeds up to 120MB/s and read up to 250MB/s, and Lexar specifies 1080p full-HD, 3D, and 4K video capture with DSLRs, HD camcorders, and 3D cameras.
Will it work in my camera if it only supports UHS-I?
Yes. The card is backwards compatible with UHS-I devices and runs at UHS-I speeds; in older non-UHS cameras and readers it performs at Class 10 speeds.
What read and write speeds should I actually expect?
Lexar rates it up to 250MB/s read (1667x) and up to 120MB/s write. Hitting the 250MB/s figure requires a UHS-II card reader; UHS-I hardware caps you well below that.
How many photos or how much video fits on 64GB?
Capacity depends on your camera's bitrate and file format, so check your body's specs. If 64GB is tight, Lexar offers this same Professional 1667x line in capacities up to 256GB.
Is the Lexar Professional 1667x reliable enough to trust on a paid shoot?
Lexar includes limited lifetime product support. Check the product listing for the current warranty terms.
