It barely took a few days for the speedy microSD Express cards to go out of stock on Amazon, as the majority of buyers would have secured a purchase to expand the storage on their upcoming Nintendo Switch 2. The biggest reason to get any of these cards is the speed upgrade, and on Amazon, you can currently get the SanDisk 128GB versions for $49.99. Sadly, if you want to get one of the higher storage models, those are temporarily out of stock.
If you are in dire need of a microSD Express card, this is the only option listed, with even the Lexar Play PRO variants unavailable at this time. While you have the option to wait until the stock is replenished, there is no telling how long that will be, and during this period, you can also risk the 128GB versions going out of stock. Regarding performance, these microSD Express cards can go up to 880MB/s, with write speeds reaching up to 480MB/s.

The sustained performance of the SanDisk can be maintained at 100MB/s, meaning that any and all programs loaded from this storage card will not run into frame drops or any other hitches. These microSD Express cards are not just designed for the Nintendo Switch 2, but are compatible with a wide array of products that can accommodate the smaller form factor.
Best of all, SanDisk rates it products to be waterproof, temperature-proof, humidity-proof, drop-proof, shock-proof, magnetic-proof, x-ray proof, and wear-out proof. In short, you are getting something nearly bulletproof and it is barely larger than your fingernails. It is highly recommended that you take advantage of this deal right away, because, like the higher storage versions, even this one can go out of stock in the blink of an eye.
