Difference Between MicroSD Express and MicroSD Cards: A Comparative Guide

Imagine a microSD card with a familiar look but a powerhouse inside—that’s essentially what a microSD Express card is. It retains the traditional shape and size of a microSD card that you’re used to seeing. However, where it truly stands out is in its performance, boasting remarkably faster transfer speeds. This makes it a fantastic option for gamers or anyone needing to move large files quickly across their devices.

The secret to its enhanced speed lies in the technology it uses; microSD Express cards leverage PCIe and NVMe interfaces, which are pivotal in speeding up data transfers. The downside? These cards usually come with a heftier price tag compared to their classical counterparts.

Introduced back in 2019, microSD Express hasn’t yet overshadowed traditional microSD cards in popularity. But as new devices begin demanding these speedy cards for optimal performance, this may soon change. For those seeking quick and efficient data transfer—be it for gaming, working on videos, or anything else—microSD Express could be just the ticket you need over a typical microSD card.

These cards are particularly well-suited to gaming handhelds equipped with UHS-I or UHS-II card readers, including popular devices like the Steam Deck, ROG Ally, Legion Go, MSI Claw 8 AI+, and the anticipated Nintendo Switch 2.

While the market isn’t brimming with options just yet, that’s about to shift, especially now that the Nintendo Switch 2 relies exclusively on microSD Express. Here are some standout choices if you’re looking to buy a microSD Express card right now.

You probably have some questions about these new cards, so let’s tackle a few common ones.

MicroSD Express vs. MicroSD: Which reigns supreme?

The microSD Express outspeeds its predecessor, offering impressive performance perks. Still, the trusty traditional microSD might still do the trick, depending on your specific needs and the devices in question. But should speed be your top priority, microSD Express is the way to go.

Do you need a microSD Express card for your handheld device?

This boils down to the specific gadget you own. For example, the Nintendo Switch 2 mandates the use of microSD Express cards to expand storage. In contrast, devices like the Steam Deck, ROG Ally, Legion Go, MSI Claw 8 AI+, and the original Nintendo Switch are compatible with older microSD options.

When did microSD Express cards hit the scene?

These cards first appeared on the tech radar in 2019. Like most innovations, it’s taken a bit of time to gain traction among consumers. But as compatibility and demand grow, we expect to see a significant shift in their usage shortly.
