Samsung’s new microSD card is faster than some SSDs

Samsung’s upcoming microSD card will offer a dramatic speed boost. The company’s 256GB SD Express microSD — the first of its kind — can read data at up to 800 MB/s, significantly faster than the microSDs you can buy today.

“To ensure stable performance and reliability for the small form factor, Dynamic Thermal Guard (DTG) technology maintains the optimum temperature for the SD Express microSD card, even during long usage sessions,” the company wrote in a press release announcing the new card. The company’s Galaxy S24 series goes big on AI, but Samsung hasn’t included a microSD slot in its flagship phones for the last four generations. So, while future AI-powered devices could benefit from the extra speeds, Samsung’s current batch of high-end phones aren’t on that list.
