AGI Technology has just revealed its latest high-speed memory card, the TF338 microSD Express. This powerful little card is made to support the new storage needs of next-gen devices, including the upcoming Nintendo Switch 2.

It’s built on the microSD Express standard and runs on a PCIe Gen 3 x1 interface using the NVMe protocol. What does that mean for users? Blazing-fast speeds. The TF338 can hit up to 800 MB/s when reading and 700 MB/s when writing. That’s a huge step up from standard UHS-I microSD cards—more than four times faster.

This puts the TF338 close to SSD-level performance, making it perfect for gamers who hate waiting on load times and creators who work with big files. Whether you’re gaming or editing on the go, this card has the power to keep up.

And don’t worry about compatibility. The TF338 works with older UHS-I devices, too, so you can use it with your current gear. It’s also tough—AGI says the card has been tested for water, dust, shock, and extreme temperatures. It’s built to last, no matter where you take it.

AGI isn’t just launching a fast card—they’re showing real commitment to portable storage that’s ready for the future. With the TF338, gamers and mobile creators now have a compact, durable, and seriously fast memory card to count on.
