Western Digital plans to release the first 4TB SD card next year. On Thursday, the storage firm announced plans to demo the product in person next week.

Western Digital will launch the SD card, which follows the SD Association’s Secure Digital Ultra Capacity (SDUC) standard, under its SanDisk brand and market it toward “complex media and entertainment workflows,” such as high-resolution video with high framerates, using cameras and laptops, the announcement said.

The spacious card will use the Ultra High Speed-1 (UHS-1) bus interface, supporting max theoretical transfer rates of up to 104 MB per second. It will support minimum write speeds of 10 MB/s, AnandTech reported. Minimum sequential write speeds are expected to reach 30 MB/s, the publication said.
