And now, Nintendo has partnered with HORI for official Switch-branded 16 GB and 32 GB SD cards. While it may be logical that Nintendo would sell official cards (these are for the Japanese launch, but there may end up being Western equivalents) the problem is in the price.
The 32 GB card is ¥7,900, or about $70 USD. But on Amazon, the high end 32 GB SD card from Sandisk is ¥2,690, or about $23 USD. Past that, if you want a cheaper version with the same amount of storage (but with slower read/write speed perhaps), you can find one for as little as ¥1,180/$10.
All of this is to say that it is probably not the smart play to purchase the officially branded SD cards because of this rather severe price mark-up. Paying three times as much as necessary just to get the official Nintendo seal of approval isnt worth it, and Im not sure why the price point is what it is here. Keep in mind these are not proprietary memory cards like what weve seen with Sony handhelds. Any SD card will work in a Switch.
