Professional 1667x SDXC card for high-resolution

The Lexar Professional 1667x 256GB SDXC UHS-II/U3 card targets professional photographers and videographers who need reliable storage for 1080p Full-HD, 3D and 4K content. Its 256GB capacity supports extended shooting sessions without frequent card changes. The card works with DSLR, cinema-quality video and 3D cameras. Backwards compatibility allows use in UHS-I devices at their maximum speed thresholds.

Sustained write performance for continuous video

UHS Speed Class 3 (U3) rating guarantees the minimum sustained write speed required for uninterrupted 4K video capture. Read transfer speeds reach up to 250MB/s, accelerating offload and post-production workflows. The 1667x rating reflects the card's peak read capability under optimal conditions. Rigorous Lexar quality testing ensures consistent performance across the full 256GB capacity during prolonged use.

Simple installation with broad device support

The full-size SD form factor inserts directly into compatible camera slots without adapters. UHS-II interface engages automatically in supporting devices, while UHS-I fallback requires no configuration. Common issues include using the card in older readers that cannot exceed UHS-I speeds, or formatting the card in a file system the camera does not recognise. Always format in the target camera before critical shoots.

Questions about this item

Does the 1667x card run hot or draw extra power during all-day 4K shoots?

The card uses UHS-II technology with a U3 rating, which is designed for sustained high-speed capture without excessive heat or power draw during extended 4K recording sessions.

My camera only has a UHS-I slot — will this 256GB card still work?

Yes, the card is backwards compatible with UHS-I devices and will perform up to the maximum speed thresholds supported by the UHS-I interface.

Can I pair this 1667x card with an older UHS-I card in dual slots without slowing the buffer?

Each slot operates independently, so the 1667x card will run at its rated UHS-II speeds in a compatible slot while the older card runs at its own UHS-I limits.
