20tb vs 22tb

Black friday time I buy a hdd.

​

Now I'm torn between a 20tb at about 17+/tb or pay more per tb and get a 22tb and also feature it in a YouTube video (I do YouTube).

​

Feels like price difference is between 350 and 450 approx. So the 20 is a better deal but would be nice to try a 22tb.

Also space is important so going for the bigger sizes is the reason for me but this here is only a 2tb difference.

​

What do you think? 22tb or 20tb hdd?
