Description
The Patriot EP Series 256GB microSDXC Express card is built to deliver next-level storage performance in compact form. Utilizing the microSD Express interface (which blends PCIe and NVMe lanes with legacy SD protocols), it surpasses traditional UHS-I limits and unlocks faster load times, rapid data transfers, and efficient handling of high bitrate video or large game files.
In a compatible card reader environment, this card achieves bursts up to 800 MB/s read and 600 MB/s write. When used in UHS-I slot devices (like many consoles or handhelds), the host falls back to UHS-I speeds (~100 MB/s read, ~90 MB/s write). This ensures broad compatibility while giving you headroom when plugged into newer hosts.
It is ideal for expanding a Nintendo Switch 2 game library, recording high resolution gameplay, or storing large media collections. The compact size means it fits seamlessly into gaming handhelds, drones, action cameras, or smartphones without adding bulk. And its robust thermal and voltage tolerances make it reliable in varied environments.
