The inception of the Nintendo Switch 2 meant that storage card manufacturers needed to deliver a workaround that would get rid of performance bottlenecks from the microSD form factor. Shortly after, the microSD Express protocol formed, and with it, a flurry of brands brought their versions of pricey storage cards barely bigger than your fingernail. Fortunately, those who were waiting for Amazon’s Prime Day 2026 sale will be pleased to know that Samsung’s P9 Express with 256GB storage is down to just $39.99, thanks to a 50 percent discount.
With speeds reaching up to 800MB/s, the Samsung P9 Express is the one upgrade that’ll benefit you in a variety of ways
The best part about P9 Express is that it sports the same footprint as the regular microSD cards, but it offers a massive performance bump in return. Thanks to leveraging the PCI Express standard, Samsung’s fastest microSD Express can reach sequential read speeds of 800MB/s, making the bandwidth four times higher than what traditional microSD cards can achieve.
Of course, with that speed boost comes extra heat generation. Samsung thought of this setback, which is why its P9 Express is protected by the company’s Dynamic Thermal Guard technology, which helps with heat dissipation. Each P9 Express card also has six protection levels to give you peace of mind for every purchase. These are temperature-proof, magnet-proof, X-ray-proof, drop-proof, water-proof, and wearout-proof.
With each purchase, you’re also entitled to a 3-year limited warranty, and even if you don’t own a Nintendo Switch 2, these microSD Express cards are backwards compatible with older standards. In short, there’s nothing stopping you from becoming the proud owner of Samsung’s P9 Express. If anything, each purchase can futureproof you for when other devices begin supporting the microSD Express standard, and that’s when the real fun starts.
