Community Reviews

This Onn 256 GB microSD Express card stands out as a cheap way to add fast storage for a Switch 2, with backward compatibility for older devices at slower UHS 1 speeds. The price looks strong versus other cards, and the same Onn line is described as working well in Switch 2 use. The main concern is reliability, since multiple cards have failed after months to a little over a year, including light use. It is a solid value if you want Express support, but long term durability is the question.

Got an Onn 512 for my Switch 2 and it works very well. I think I paid around $80. If you're on the fence about this brand; don't be bc a major SD manufacturer actually makes the hardware. Onn buys and rebrands them

My Onn 512 gb failed after like 7 months of mostly sitting idle (the switch2 is only used once a months top on average). Tried to get warranty replacement (supposedly a 1 year warranty) but Walmart couldn't help and only gave me a phone number, which I never called and forgot about until the year had passed

May or may not be worth the trouble, but if you paid by credit card, some cards extend the warranty as a card perk.

This wasn't that funny the first time you posted it, and has not increased in cleverness as you repeatedly posted on every SD card price increase thread.
awww, someone is grumpy today...!

Neither code worked. Luckily I have couple of $10 off $50 from Amex Offer and used that instead. Urgent need one for a card for security cam.
