Samsung's SD Express microSD card, based on the SD Express interface, marks an industry-first achievement. Developed in collaboration with a customer, this high-performance microSD card delivers SSD-comparable performance in a compact form factor. Unlike traditional microSD cards limited to UHS-1 interfaces with read speeds of 104MB/s, the SD Express microSD card boasts significantly enhanced performance, reaching up to 800MB/s sequential read speed. This represents a substantial improvement over SATA SSDs (up to 560 MB/s) and traditional UHS-1 memory cards (up to 200 MB/s), enhancing computing experiences across various platforms.

The new 1TB UHS-1 microSD card from Samsung utilizes cutting-edge 1-terabit (Tb) V-NAND technology, stacking eight layers of the company's 8th generation V-NAND within a microSD form factor. This achievement brings high-capacity storage previously exclusive to SSDs into the microSD realm. The 1TB microSD card undergoes rigorous testing and offers reliable performance even in harsh conditions, featuring water protection, extreme temperature resistance, drop-proof design, wear-out protection, as well as X-ray and magnetic protection.

The 256GB SD Express microSD card will be available for purchase later this year, while the 1TB UHS-1 microSD card is scheduled for launch in the third quarter.
