When you compare the capabilities and the cost it seems like it's a no brainer to go with SSD unless it's archival in which case I'm pretty sure a spinning disk that spends most of its life asleep will last longer than 10 years assuming that grease and other critical components don't get critically fragile merely by age (if it takes heat plus work plus time then sleeping drives are cooler and will last longer).

I feel like in today's world, there's almost no reason to go with HDD over SSD. SSDs offer better performance and life span. Even though they cost more per storage capacity, they're still not ridiculously expensive in the grand scheme of things.

Looks like we have a sats vote between two perspectives here. V ^ I'm not sure but I like to use old drives and for backups of a node, HDD I think are still ok, you set the drives to sleep in the bios or wherever and you can have multiple backups on a cheaper HDD so you can have multiple backups which is better than the same cost with only one backup.
