MicroSD Express vs. MicroSD Cards: Understanding the Differences

A microSD Express card holds the same compact design as the typical microSD card you’re used to. However, what sets it apart is its impressive speed performance—it’s significantly faster, making it a great choice for gamers and anyone needing to transfer large files efficiently on their computer. This speed advantage comes from its use of PCIe and NVMe interfaces for data transfers.

One thing to keep in mind is that these advanced features come with a higher price tag compared to standard microSD cards. Although this technology has been available since 2019, it hasn’t quite matched the popularity of traditional microSD cards. That could change as more devices start to require these faster cards for optimal performance.

If you’re after a flash-memory card that can handle quick data transfers, whether for gaming, video work, or other demanding tasks, you might find the microSD Express to be a better fit than its traditional counterpart. It’s particularly useful for handheld gaming devices equipped with UHS-I or UHS-II card readers, such as the Steam Deck, ROG Ally, Legion Go, MSI Claw 8 AI+, and the upcoming Nintendo Switch 2.

Currently, the selection of microSD Express cards is somewhat limited, but with the Nintendo Switch 2 exclusively using this type of memory, we can expect more options to arrive soon. Let’s look at some of the top picks available now for microSD Express cards.

To help with any lingering questions you might have, here’s a quick FAQ regarding microSD Express Cards.

MicroSD Express vs. MicroSD: Which should you choose?

If speed is a priority, microSD Express outperforms the traditional microSD with its faster transfer rates. However, if your needs are more basic, a regular microSD might be more than sufficient, depending on your device and usage. For those looking for the quickest option, go for microSD Express.

Is a microSD Express Card necessary for my handheld console?

It’s largely dependent on the device. For the Nintendo Switch 2, it’s a must as it’s the only compatible external storage option. But models like the Steam Deck, ROG Ally, Legion Go, MSI Claw 8 AI+, and the original Nintendo Switch work just fine with older microSD cards as well.

When did microSD Express Cards hit the market?

This technology debuted in 2019. Like many innovations, it has taken some time to gain traction and become widely adopted in the mainstream.
