Lexar 128GB 17p SDXC 2000x UHS-II U3 V90 CYU memory card

128 GB SDXC card for professional 4K capture

The Lexar 128GB SDXC card is built for photographers and videographers who need reliable high-speed storage. Its UHS-II interface supports read speeds up to 300 MB/s and write speeds up to 260 MB/s. The V90 rating guarantees sustained performance for demanding 4K video workflows.

Full-size SD form with 17-pin UHS-II interface

The card uses the standard full-size SD shape with a 17-pin contact layout required for UHS-II speeds. A mechanical write-protect switch on the casing prevents accidental data loss. The bundled SD reader provides a direct USB connection for fast offloading without a camera cable.

V90 sustained write speed decides 4K suitability

The Video Speed Class V90 rating means the card maintains at least 90 MB/s continuous write throughput. This specification determines whether the card can handle high-bitrate 4K recording without dropped frames. Buyers who need higher capacity for extended shoots should consider larger cards.
