Because of the fact that it is listed at Best Buy, and its accompanying price ($400!), I'm inclined to believe that this is the first legitimate micro sd card available in a size larger than 256GB. At 400GB its quite the step up at that. SanDisk is a reliable brand too, check out Best Buy's listing here:

A couple of other stores list the same card at only $250, but when it comes to sd cards and buying them online, I'm always incredibly wary of buying one that is at a considerably smaller price than other sources as often they are faked to only have a fraction of the amount of storage.
Regardless, $250 or $400 would be too much for me to invest in as it stands. But hopefully as we've seen in years past, these will start to catch on and the price will reduce significantly as more and more are produced. A 400GB micro sd card would really be perfect for something like the Nintendo Switch. While a 200 or 256GB micro SD card will work well enough, its becoming clear that they will quickly fill up as more and more developers release these larger in sized games on the system.
