Product description: Silicon Power MicroSD 1TB (Nintendo Switch Operation Verified) 4K Compatible, UHS-I U3 V30 A2 Standard Ultra HD Large Capacity 1TB Maximum Speed 100MB/s
Looks like a decent price for 1TB micro SD at this speed from a known brand.
Even better if you buy 2 to take advantage of the 12% off coupon.
There should be other eligible items to use the coupon with, but I wanted 2 cards anyway so I didn't look further.
Sold by Amazon Japan.
I ordered last night and the ETA is 30 July.
Tech is insane.
