Professional 1667x SDXC card

The Lexar Professional 1667x is a 128GB SDXC memory card built for photographers and videographers who need reliable high-speed capture. It uses UHS-II technology with U3 speed class to handle demanding workflows.

Thermals noise and power

As a solid-state memory card it has no moving parts and draws minimal power from the host device during normal operation. Silent performance and low heat output are inherent to the flash storage design.

Sustained load behaviour

The card maintains read and write speeds of 250MB/s for extended transfers and continuous 4K video recording. U3 rating guarantees the minimum write performance needed for long shoots without dropping frames.

Questions about this item

How do I install this Lexar 1667x SDXC card in my camera, and what step do people often miss?

Insert the card label-side up until it clicks; the step many miss is formatting it in-camera before first use to ensure the 128GB capacity and UHS-II speeds are recognised correctly.

What maintenance or replacement will this 128GB Lexar card need over time?

No scheduled maintenance is required; replace the card if write speeds drop below 250MB/s, errors appear during 4K recording, or after heavy rewrite cycles typical of professional video workflows.

What limit appears first when I shoot long 4K clips continuously on this card?

Sustained write speed of 250MB/s is the first bottleneck; if the camera's bitrate exceeds that, recording may stop or frames drop before the 128GB capacity fills.
