Huh? Solid state drives do certainly fail, especially consumer parts.
Ideally, IF Apple were to source the best NAND silicone for reliability, and IF they had the best wear leveling algos implemented in NAND controller FW, and IF MacOS had optimal IO for write calls, and IF the soldering, temperatures, and voltage regulation to the NAND and controller were to be kept within ideal spec, then we could safely assume they might never fail, but that's a lot of IFs, and is why SSDs still fail quite a bit despite no moving parts.
Which is why I refuse to buy PCs/laptops with soldered storage. That's like buying a car with the brake pads permanently attached to the chassis.
For most people this advice doesn’t matter but if you do work on your laptop that involves tons and tons of writes (e.g. local Docker work with lots of huge container builds and multiple VMs) then over provisioning is good.
It’s also very good advice for any server deployment you want to be reliable. If I were deploying a good old fashioned database box to be super reliable I’d oversize the SSD as much as possible (coupled with hot swap and mirroring).
This probably varies from person to person though. Someone who's shuffling around tens or hundreds of gigabytes a video per day for example probably burns through them much more quickly than I do, with the most disk intensive thing I do being software development.
And the SSD fails were AFAIK never due to excessive wear from the user side but simply the SSD giving up the ghost out of nowhere probably due to faulty FW or faults in the NAND fabrication of RAM of the cache. SSD have enough points of failure despite no moving parts.
HDDs would also fail more gracefully, like you'd usually get SMART warnings, crashes, strange noises before they'd inevitably die, but SSD simply just stop working one day out of the blue.
As far as failing gracefully, for me HDDs have been a mixed bag. Some have shown warning signs beforehand but I've had a few that just up and died one day with their performance up until that point having been business as usual.
Same with my old corporate HP. SSD (SK Hynix) died within one year.

Do you also sell tens of millions of them per year?
There's been enough HN threads where people bought framework laptops only to ditch them a few weeks after as they are nowhere near a macbook no matter how much you try to oversell it.
