Lexar Professional 1667x 64GB SDXC 2-Pack

This two-pack supplies a pair of UHS-II SDXC cards, each rated at 64GB capacity and 1667x speed. They target photographers and videographers who need reliable media for 1080p Full-HD, 3D and 4K capture with read transfers up to 250MB/s.

Upgrade from slower UHS-I or Class 10 cards

Moving up from standard UHS-I media removes the bottleneck that stalls burst shooting and 4K recording. The jump is worth it when your camera supports UHS-II and you regularly fill buffers or wait on offloads.

Fits UHS-II slots and works in UHS-I devices

Cards slot into any SDXC-compatible camera, recorder or reader; UHS-II hardware unlocks the full 250MB/s read rate while UHS-I hosts fall back to their maximum supported speed. The twin pack lets you rotate media during long shoots without changing cards mid-session.

Questions about this item

Will the 64GB SDXC cards fit my camera's UHS-II slot?

Yes, the Lexar Professional 1667x cards are standard-size SDXC UHS-II cards that fit any SDXC or SDHC slot; they are also backwards compatible at the highest UHS-I speeds.

What is the correct way to insert the card so the 1667x read speed works?

Align the label facing the camera's label side and push until the card clicks; the extra row of pins on the back engages only when fully seated — partial insertion drops the card to UHS-I speeds.

How often should I replace these cards if I record 4K video at 250MB/s read?

Lexar rates the cards for professional workloads; replace them when you notice sustained write slowdowns, file corruption, or after roughly two to three years of daily 4K capture.
