MicroSD Express vs. MicroSD Cards: Understanding the Differences

What exactly is a microSD Express card, you ask? Well, it’s essentially the upgraded version of your typical microSD card, keeping the same compact shape and size. What sets it apart, though, is the blazing-fast transfer speeds it offers, perfect for gaming and zipping large files between devices.

These speedier transfers are thanks to microSD Express leveraging PCIe and NVMe interfaces. However, this advancement in technology does come at a cost—literally. MicroSD Express cards tend to be pricier than their traditional counterparts.

Although this technology has been around since 2019, it hasn’t quite stolen the spotlight from standard microSD cards yet. However, as more of these cards enter the market and are needed for new devices to function optimally, this trend is expected to shift.

If speed is what you seek in a flash-memory card—whether for gaming, video editing, or hefty file transfers—microSD Express might just tick all your boxes over a standard card. They’re tailor-made for gaming consoles with UHS-I or UHS-II card readers, like the Steam Deck, ROG Ally, Legion Go, MSI Claw 8 AI+, and the anticipated Nintendo Switch 2.

Now, when it comes to picking the best microSD Express cards, the selection isn’t vast at the moment. But things are looking up now that the Nintendo Switch 2 exclusively supports this format, likely spurring a production boost.

In case you’re still wondering about microSD Express cards, let’s tackle some common questions.

MicroSD Express vs. MicroSD: Which one gets the trophy?
MicroSD Express is the speedier contender, offering greater performance benefits. Yet, a traditional microSD might still suffice for your needs depending on your device and what you’re using it for. If speed is non-negotiable, an Express card is the way to go.

Do I need a microSD Express Card for my handheld console?
That really comes down to the device. The Nintendo Switch 2 requires microSD Express Cards for additional storage. Other handhelds like the Steam Deck, ROG Ally, Legion Go, MSI Claw 8 AI+, and the original Nintendo Switch, however, are still compatible with older microSD cards.

When did these cards make their debut?
MicroSD Express Cards have been around since 2019. Like many technological innovations, they’ve taken some time to gain traction and become widely adopted.
