Once you write ~400TB or whatever it’s rated for on a consumer SSD it dies.
Not really. Tests and my experience show this is just a pure warranty number. Meaning the manufacturer guarantees that the drive will do at least this many writes without failing and it reaching it also voids your warranty. However, you can usually expect 2x as many writes, although 10x and more is also not unheard of.
HDDs can take a lot more writes before dying.
They are actually often not rated for a ton of reads and writes. But once again this is more of a warranty thing and HDDs are usually unmetered so…
The Seagate Ironwolfs 18TB have a Workload Rate Limit (WRL) of 300TB/year, as do some WD models. Unlike SSDs this WRL includes not only writes but reads as well. (page 2, end) If you do a monthly scrub you already have 216TB of reads so it can be safely assumed that a lot of customers blow well past these numbers. This limit is in use since the 2TB drive area and simply does not fit 9x larger drives. ServeTheHome talked about this years ago.

HDDs are not unmetered warranty wise. My new 18TB Seagates has a something like 150TB/year write endurance (TBW) if I want to keep the warranty.

Huh good to know, thanks!
