you guys are the pros - external drive ideas

So YES i did google this, BUT everytime I google it alls it talks about is transfer speed.

I don't care about transfer speeds, I care about the amount it can hold and especially if it is safe to keep my stuff there for long periods of time. I have a fear of buying a cheap external drive/usb storage device because I'm terrified if it'll corrupt my data.

I'm hoping for 1-2 TB

So, does anybody have any suggestions for a higher capacity but low speed external drive? (low speed because I assume they might be cheaper if they're slower?)

also: would there be a better option of cloud-based storage like google photos or drive? I know when I used google photos they fucked my concert videos into 4 pixel oblivion, so It's definitely not my first option, but I'm curious if somebody has alternatives.
