Rumor: Nintendo Switch supports Micro SD cards up to 128GB, no external HDD support

A report by Let’s Play Video Games says that the Nintendo Switch will support memory expansion via Micro SD card the same as the New Nintendo 3DS. The Nintendo Switch development hardware also supports Micro SDXC cards up to 128 GB in size. They have also reported that the Nintendo Switch dock will not support external USB drives like the Wii U.

It is currently unclear if this upper limit will be reduced on the retail model, but the development model of the Switch does support running software directly off the Micro SD card as you would off the internal memory or a game cart.
In addition, a source close to the production of the Switch reveal trailer has informed us that the Micro SD slot on the Switch can be located underneath the handheld’s kickstand on the model shown in the reveal trailer.
