At Computex 2026, SanDisk showcased its latest SDUC (Secure Digital Ultra Capacity) memory cards boasting massive storage capacities of 4 terabytes (TB) and 8TB. These developments mark a significant step forward in SD card technology, aimed at professionals and enthusiasts who require expansive storage for high-resolution content and advanced gaming experiences.

Large Capacity Cards with Reliable Speed Specifications

The newly presented 4TB and 8TB SDUC cards are engineered to maintain a minimum sustained write speed of 10 megabytes per second (MB/s). Additionally, the cards demonstrate random input/output operations per second (IOPS) of 1500 for reading and 500 for writing. This level of performance caters to demanding applications such as 4K and 8K video recording, high-speed burst photography, and rapid file transfers in portable devices.

Alongside these high-capacity models, SanDisk also introduced a 4TB Extreme Pro card that offers increased write speeds starting at 30 MB/s. This product line extension addresses professionals who prioritize faster write capabilities alongside considerable storage space.

With these advances, SD cards now accommodate the growing demands of modern digital media workflows, gaming consoles, and other portable technology platforms requiring extensive and reliable memory solutions. The enhanced capacities and performance guidelines also align with the SD Association’s efforts to standardize next-generation removable storage types.

While pricing and exact release dates remain undisclosed, the appearance of these cards at Computex indicates imminent availability in the consumer market. Users involved in photography, videography, and gaming are expected to benefit most from the expanded storage options paired with steady data handling speeds.

The introduction of these cards adds further momentum to the evolution of storage technology, providing new possibilities for content creators and device users who routinely deal with large-scale data, ensuring better efficiency and convenience in managing digital assets.
