alt Hacker News>There was quite a bit of discussion about that when the M1 first came out, but none of it really seemed to have happened six years later.
1. How do you know nothing happened? Define nothing in this case. Do Mac users check and report their SSD wear anywhere?
2. Didn't the OG 256gb M1 have 2 128MB NAND chips instead of one 256 meaning better wear resistance?

As a data point: I got a 14" MacBook Pro with a 512 GB SSD the first day it was available in 2021, and I've used it daily since then.
According to the SMART data ("smartctl -x /dev/disk0"), the SSD "percentage used" is 7%, with ~200 TBW. At this rate, the laptop will probably outlive me.
If swapping was causing SSDs to fail on M1 Macs, we would never see the end of the hysterical articles about "NANDgate". Since we haven't seen any in all these years, it's seems pretty certain it's not happening.
