Honestly you should be more worried about which standard will still be around in 15+ years.
A USB-C external hard drive is probably the best bet.

I dont see sd cards or usb going anywhere. Cards have pretty much stagnated to sd and we still have support for usb 1 which is like 20 years old.

Too expensive for too little capacity. Also only lasts like 60 years at most

So what? Get another one halfway down the road.
