What Is microSD Express? Why It’s So Much Faster Than Regular microSD Cards
1 min read
Summary
The latest in microSD card technology is microSD Express, which integrates PCI Express (PCIe) and NVMe interfaces into the microSD form factor, allowing for higher data transfer rates than traditional microSD cards.
The cards are around 300MB/s faster than the fastest standard UHS-III cards in sequential read speeds and use NVMe technology to enable much faster data processing.
MicroSD Express cards are compatible with devices that use regular microSD cards, but when used in an older device, microSD Express defaults to the speed of the older technology of UHS-I.
Currently, very few devices support microSD Express, but the Nintendo Switch 2 does, and it requires microSD Express cards to work.
As technology develops, it is likely that microSD Express will become more widely used and cheaper as it becomes more widely adopted.
