San Disk came out with the new 1.5 TB Micro SD Card. It works great for Nintendo Switch, Steam Deck, ROG Ally and other devices with the card slot. That's assuming your device supports a large card.
Just got a 256gb Sandisk Micro SD and it's completely flat but my 128gb Sandisk from 2017 is not flat and the one thats flat is more difficult to remove in my case. Its weird.
i like new sizes because it lowers the price of existing sizes 1.5tb is a bit much for me but now i can easily afford a couple 512's or handfull of 256s
