Design of an SD card.

SD cards are very common types of storage mediums thatNintendo began using in theWii era. The Wii, unlike theNintendo GameCube, has internal memory where players can save their game data, or even on SD cards, especially in cases where the internal memory runs out of storage. SD cards can store the Wii's channel data and some non-save game data, such assnapshots inSuper Smash Bros. Brawl, though the game also allows snapshots to be saved on the internal storage. The Wii,Nintendo 3DS, andWii U all support SD cards up to 32GB in memory, though in the Wii's case, before the System Menu 4.0 update in March 2009, it could support only up to 2GB standard SD cards, not any SDHC cards.Super Smash Bros. Brawl and many other games are incompatible with SDHC cards, especially if they were released before the Wii gained SDHC card support.

The Wii has an SD card button in the lower left corner of the Wii Menu. If the button shows up as blue instead of gray, meaning the Wii acknowledges that an SD card is inserted, clicking on the button will show a special menu with gray boxes on black, showingVirtual Console andWiiWare games that are stored on the SD card, including any ofSuper Mario franchise.

TheNintendo Switch usesMicroSD cards for internal storage, allowing for up to 2 TB. Two official Nintendo microSD cards designed especially for the Nintendo Switch areSuper Mario-themed: the red 128GB microSD card with aSuper Mushroom and the yellow 512GB microSD card with aSuper Star symbol.
