"As for writes, at 1 gb a day - far more than my current rate of data use - it would take the same 114 years to reach 40 tb."

Maybe it works for author's very specific system or use-case, but on my personal MBP laptop with very occasional usage pattern--some days I do not use it at all during the week--I end up with 10 GB per day of writes on average. That way it will be 11.4 years already, not so many. And I do not do something very disk-expensive on it like torrents downloading or database testing, only some general development task, watching online videos, web surfing, docs, etc.

I have an NVME SSD as a boot drive in my desktop and three years and change in (say 1200 days) it’s used 40tb of write (out of an advertised 400tb endurance so I’m not too worried). That works out to about 30gb of writes per day, which seems about right for medium to heavy use.

I guess what I’m saying is that for modern SSDs I don’t think write endurance is a binding constraint in most cases.

For client/consumer SSDs, most vendors seem to view 50GB/day as plenty of write endurance for mainstream, non-enthusiast products. Virtually all retail consumer SSDs have a warranty that covers at least that much, and usually several times more for larger drive capacities (since write endurance is more often specified in drive writes per day).

Coincidentally 50GB/day is what Chrome craps out to the hard drive during few hours of usage, doing such clever things like "caching" YT videos (YT player NEVER reuses data, and rewinding always generates new server fetch with new randomly generated URL).

How much RAM do you have? And how many Chrome tabs?

[ololobus]

16 GB of RAM and I use Safari mostly and Firefox from time to time with less than 20 tabs usually (less than 10 in average, I guess).

I check Data written in the Activity monitor — Disk.
