Bit more then 150TB TBW
I really hope the reduced writes for ext4 are as good as they claim.
Depends on the model: per Kroll Ontrack, which I would hope know what it's talking about, 'A typical TBW figure for a 250 GB SSD lies between 60 and 150 terabytes written [...]' Now, Heise's famous 2016 test showed that drives will handily exceed their stated longevity - but, then, that's what you'd expect: if a bridge good to 1,000 tonnes of traffic collapsed when 1,001 tonnes drove over it it'd be terrible, so there's a margin of error built in. Same with SSD longevity: if the manufacturer says 150TBW, you might be good up to 600TBW or more - but, that said, you've no room to complain if it hits 151TWB and says "welp, that's me."
