The Switch allows you to use pretty much any old microSD card as long as it has a transfer speed of at least 60 MB/s, but if Nintendo aims to bring their games more up to modern standards, that’s probably not going to cut it anymore. That said, the M.2 NVMe SSDs used in next-gen consoles and the Steam Deck may be too hot and power-hungry if Nintendo aims to stick to the slim Switch form factor with their next hardware, so what do they do?
Well, we may have an answer in
Samsung’s newly-announced line of SD Express microSD cards. These cards, which will launch with a 256 GB card later this year, to be followed by a 1 TB option, offer 800 MB/s transfer speeds. Perhaps most interesting, Samsung lets slip in their press release that these cards resulted from a “successful collaboration with a customer to create a custom product.”
...
If Samsung’s new SD Express tech is indeed going to be in the Switch 2, the 800 MB/s transfer speeds will be around 10x as fast as those of the OG Switch, which could potentially result in, say, backward compatible games loading nearly instantly. That 800 MB/s is still short of the 5,500 MB/s transfer speed of the PS5’s SSD, but if the Switch 2 is aiming for PS4-level power and visual fidelity, perhaps those full SSD speeds aren’t really required.
