As an average consumer/data hoarder, why not store those on cheap spinning HDD's? They can stream the data fast enough, and modern NAS hardware gives you easy RAID too. You don't really need super-quick random access to multiple TB's of data, so HDD storage is probably good enough.

HDD is really not fast enough if you're going to be doing a RAID rebuild with a 18TB HDD

I’m running several that large or larger in a Synology.

Adding a drive takes a week. Replacing a drive a slightly quicker, but rebuild times are no joke.

It's plenty fast enough for my N+2 ZFS Raid, but I'll admit that that time is still measured in days.
