The PNY microSD Express Flash Memory Cards are here, just in time for the upcoming Nintendo Switch 2 release and compatible with current gaming handhelds. Offering up to a 4.4x speed increase over standard UHS-I microSD cards, these PNY microSD Express cards boast speeds of up to 890MB/s read and up to 750MB/s write!
Why microSD Express?
Simply put, microSD Express cards are much faster than traditional microSD cards—assuming you have the correct device to take advantage of their more rapid speeds. Current microSD cards, depending on the manufacturer and type, tap out at around 300MB/s read and 260MB/s write speeds. On the other hand, UHS-I cards are much slower, only getting up to 170MB/s read and 90MB/s write speeds. While gaming, you don’t want to be waiting around for your game or the next level to load, and that’s where microSD Express cards come in. With speeds of up to 890MB/s read and 750MB/s write, your games will load faster and run smoother.

With PNY’s latest cards, gamers can purchase microSD Express cards in either 128GB or 256GB capacities. This makes them a great addition to your Nintendo Switch 2 (if/when you get one) and backward compatible with devices that support UHS-I and UHD-II speeds.
Why PNY?
I’ve been reviewing PNY’s offerings for years and can honestly say that I’m a fan of their products. These microSD Express cards from PNY are crafted with unique heat dissipation designs for maximum cooling efficiency. The built-in microSD thermal monitoring and intuitive adaptive technology automatically adjust to keep your microSD card running efficiently and at optimal temperatures.
Even better, PNY ensures that these cards are magnet, shock, temperature, water, drop, x-ray, wear-out, and even humidity proof. Plus, they come with a lifetime limited warranty, giving you peace of mind that they’ll last for years to come.
