Silicon Power’s new 256GB SET320 microSD card boasts read speeds of up to 820 MB/s, making it faster than a standard SATA SSD and eight times faster than typical microSD cards. This impressive speed is achieved through a new interface, PCIe Gen 3×1 and NVMe via SD 7.0, making it the first ‘SD Express’ microSD card. The card is designed for AI-driven applications and offers backward compatibility with existing devices, though users will miss out on the maximum speed.
