Samsung's P9 microSD Express card is on sale for $80, a 33 percent discount from its usual $120 price. The 512GB card offers transfer speeds up to 800MB/s, making it significantly faster than standard microSD cards. This deal represents one of the best prices we've seen for this Switch 2-compatible storage expansion.

MicroSD Express cards are relatively new to the market, gaining traction only after the Nintendo Switch 2's release last year. These cards are the only storage solution compatible with the Switch 2 for expanding its capacity. With limited options available in this format, the P9 has earned a spot on our list of best microSD cards for the Nintendo Switch 2.

The P9 isn't limited to just the Switch 2 - it's also compatible with the Steam Deck and other gaming consoles that support the microSD Express format, plus cameras and other devices. While load times remain similar across all microSD Express cards, the P9's superior transfer speeds make moving games and data noticeably faster, addressing storage constraints for gamers who need extra space.
