Samsung today announced two new microSD cards, one of which has blazing-fast read speeds, even faster than SATA-based SSDs within PCs. Samsung revealed in a press release that the company has begun sampling 256GB microSD cards based on the SD Express standard, which is the company's first microSD card to support the standard.
This means that the card can have a maximum sequential read speed of up to 800 MB per second. That's four times faster than a regular UHS-1 microSD card, and even faster than the maximum read speed of a SATA SSD, which has a limit of 560MB per second.
According to Samsung, the speed of the 256MB SD Express microSD card will provide better overall performance for PCs and smartphones. The microSD card also features Dynamic Thermal Protection (DTG) technology, which ensures that the temperature inside the card remains stable even after prolonged use.
Samsung also announced that it has started mass production of the 1TB version of the Pro Plus and Evo Plus MicroSD card products. They stack eight layers of Samsung's V-NAND in a small card design. "The 1TB microSD has passed the industry's most rigorous test setup and is reliable even in challenging environments, with features such as water resistance, extreme temperature resistance, drop resistance, wear protection, and X-ray and magnetic protection," the company says.
Samsung's 256GB SD Express MicroSD card will be available later this year, while the 1TB Pro Plus and EVO Plus MicroSD cards will be available in the third quarter of 2024. But the company hasn't revealed the new microSD card's **.
