SD card to increase memory

When I bought the Trezor T, I thought the sd card would add extra memory not extra security.

It would be good to extend the memory using the sd card

to do what ?
Unlike some wallets, trezor requires memory to add the coin app. All operations are on the suite. So what do you want more memory to do?

I’m a total newb to trezor and bought one rather than buying ledger. Ledger has a memory limitation to the apps it holds as you have to download several apps for holding several coins. I don’t know if Trezor has this limitation but just assume size limits could become an issue just like Ledger, I don’t know though, so bought it to try it instead of ledger which has app size issues if you hold a range of different coins.

trezor has no problem like this.
