Heavily depends. If you want to use it as long-term cold storage you absolutely should not use SSDs, they're losing data when left unpowered for too long. While HDDs are also not perfect in retaining data forever, they won't fail as quickly when left on a shelf.
Good and true point, but arguably most NASs are built to be used, not to be not-used…
Well, they arguably can also be used as one big long-term storage. Not sure who'd need to save so much data for a long time, but there surely will be at least some people who do and buy the "modern solution" over old HDDs thinking they're better in general. As the "family backup" for example, or as cold storage solution in faculties that can be quickly accessed if needed.
Read somewhere about a professor who used SSDs to "permanently" store important data on SSDs (perhaps in the comments of the article above) for a few years. Well, wasn't that permanent…
HDDs die faster when running because they have to spin though.
To my knowledge it isn't them constantly running that wears them out most, but spinning up and down very often. Weren't NAS drives designed to never spin down for that very reason?
This is partially true but SSD's do not spin at all.
I have had many a NAS drive fail on me in the past.
