What is a microSD Express card?
A microSD Express card is a next-gen microSD card that has basically the same shape and physical size as a traditional microSD Card.
The difference is that MicroSD Express has much faster transfer speeds, making it ideal for gaming or transfering large files on a computer.
These faster transfer speeds are accomplished because microSD Express uses PCIe and NVMe interfaces to transfer data.
MicroSD Express Cards have been around since 2019, but they haven’t been as popular as traditional microSD cards, yet. This will likely change as more of these devices come out.
If you want a flash-memory card that can transfer data quickly whether that be for gaming, video transcoding, or more then the microSD Express might suit your needs better.
As such, microSD Express cards are ideal for gaming handhelds with UHS-I or UHS-II card readers such as the Steam Deck, ROG Ally, Legion Go, MSI Claw 8 AI+, and Nintendo Switch 2.
