Our editorial take on the Lexar 256GB Professional 1066x UHS-I SDXC Memory Card (SILVER Series, 2-Pack)
The Lexar Professional 1066x SILVER series firmly establishes itself as a go-to workhorse card for a huge range of creators. While it's a UHS-I card and does not offer the bleeding-edge speeds of the more expensive UHS-II format, its performance is more than sufficient for the vast majority of shooting scenarios. It confidently handles high-resolution still photography, burst shooting, and up to 4K video capture without issue. This series hits a critical sweet spot, delivering reliable, professional-grade performance at a price point that presents outstanding value, especially in multi-pack bundles.
It is important, however, to understand its place in the market. For professionals shooting very high-bitrate video formats or those who require the absolute fastest data offload speeds to optimize their workflow, stepping up to a UHS-II card like Lexar's own GOLD series is the logical choice. But for everyone else, from serious hobbyists to working photographers and videographers, the 1066x SILVER series offers a nearly perfect blend of speed, reliability, and cost-effectiveness. It is a smart, practical investment in your everyday creative toolkit.
- Excellent performance and speed for the UHS-I class.
- Outstanding value proposition, especially in 2-pack bundles.
- Reliably handles high-resolution stills and most 4K video recording.
- Backed by a reputable brand known for professional-grade memory.
- Widely available in both SDXC and microSDXC formats.
- Slower read and write speeds compared to premium UHS-II cards.
- May not support the highest bitrate or frame rate video recording modes on some cameras.
