Professional 128GB UHS-II SDXC Card

The Lexar Professional 1800x SDXC UHS-II card provides 128GB of storage for photographers and videographers using DSLR or mirrorless cameras. It supports Full HD and 4K video recording with a V60 rating guaranteeing a minimum sustained write speed of 60 MB/s. Maximum read speed reaches 270 MB/s while maximum write speed reaches 180 MB/s. This gold-series card is built for professional workflows requiring reliable high-speed capture.

Installation and Compatibility

The card inserts into any standard SDXC UHS-II slot and functions immediately without drivers or software. Write speeds will drop to the host device's maximum capability if the camera or reader only supports UHS-I or lower speed classes. Physical durability features include water, shock, vibration, X-ray and temperature resistance to protect data in harsh field conditions. No configuration is required beyond formatting in the camera before first use.

UHS-II Interface Limits

The UHS-II interface enables the rated 270 MB/s read and 180 MB/s write peaks, but actual throughput depends entirely on the host device's controller and firmware implementation. Devices limited to UHS-I will restrict performance to their maximum supported speeds, typically well below the card's peak potential. The V60 classification ensures 60 MB/s minimum write for 4K video, yet sustained rates vary with camera buffer architecture and codec bitrate. A UHS-II reader is necessary to achieve the fastest file transfer rates to a computer.
