Sources have revealed that the Nintendo Switch developer model supports Micro SDXC cards up to 128gb in capacity. The SD card slow is apparently located in the actual Switch tablet under the kickstand.
The other piece of information to come out of the latest reports is the fact that the Nintendo Switch won’t support external hard drives. This makes a lot of sense as the Nintendo Switch is essentially a portable console as well, so it wouldn’t make a whole lot of sense having things connected to the dock.
I guess the biggest surprise in all of this is the fact that the developer versions of the Nintendo Switch only have 32gb in storage. It’s unclear whether this will make it over to the final retail version, but there’s a high probability that Nintendo will want to keep costs down. With the Switch using cartridges, it’s unlikely that you’ll need to install game data to the actual console.
