I could be wrong, but I believe the general consensus is along the lines of "SSDs for in-use data, it's quicker and wants to be powered on often. HDDs for long-term storage, as they don't degrade when not in use nearly as fast as SSDs do.

I'd imagine HDDs also don't like not spinning for years(as mechanical elements generally like to be used from time to time). But at least platters itself are intact

I've been going through stack of external USB drives with laptop disks in them. They're all failing in some form or another. I'm going to have to migrate it all to a NAS with server-class drives I guess

At the very least, you can usually still get the data off of them. Most SSDs I've encountered with defects failed catastrophically, rendering the data completely inaccessible.
