Description
The Lexar Professional 1667x SDXC UHS-II card is engineered for mid-range and professional DSLR cameras and HD camcorders. Leveraging UHS-II technology (U3), it delivers read transfer speeds up to 250MB/s (1667x), allowing users to capture and transfer high-quality photos and 1080p Full-HD, 3D, and 4K video with ease. This card is backward compatible with UHS-I devices, performing at maximum UHS-I speed limits to ensure versatility across various hardware setups.
This product is for:
- Professional photographers shooting high-resolution RAW images and rapid-fire burst sequences.
- Videographers requiring stable V60 Video Speed Class for consistent 4K video recording without dropped frames.
- Content creators looking to reduce file transfer times during the data offloading and editing process.
- Enthusiasts using mirrorless cameras who want UHS-II performance at a competitive price point.
- Action sports photographers who need reliable write speeds to clear camera buffers quickly during critical moments.

Using the Lexar 1667x transforms the digital capture experience by minimizing the "buffer full" lag often encountered during high-speed burst shooting. The V60 rating ensures that video recording remains smooth and stable, even at high bitrates required for professional cinematography. During post-production, the 250MB/s read speed allows for rapid offloading of large files to a workstation, streamlining the transition from the field to the editing suite and improving overall productivity.
Compared to standard UHS-I cards, the Lexar 1667x offers nearly triple the read speed, making it a superior choice for high-volume workflows. While the Lexar 2000x series provides even higher speeds for elite professionals, the 1667x serves as a more cost-effective "sweet spot" for users who need UHS-II reliability and V60 video support without the premium price of top-tier cards. It significantly outperforms V30-rated cards by offering a guaranteed minimum sustained write speed of 60MB/s.
Q&A:
- What is the difference between UHS-I and UHS-II? UHS-II cards feature a second row of pins that allow for much faster data transfer rates compared to the single row found on UHS-I cards.
- Can I use this card in a UHS-I camera? Yes, the Lexar 1667x is backward compatible, though it will operate at the maximum speed supported by the UHS-I host device.
- Is this card suitable for 4K video? Yes, the V60 rating guarantees a minimum sustained write speed of 60MB/s, which is more than sufficient for most 4K video bitrates.
- How does the 1667x speed rating translate to MB/s? The "x" rating is based on the original CD-ROM speed of 150KB/s; therefore, 1667x equals approximately 250MB/s.
- Does this card come with a warranty? Lexar provides a limited lifetime warranty for the Professional 1667x series, ensuring long-term reliability and peace of mind for professional use.
