SSD health

[unblocktheplane]

I use a third-party Menubar app called SSDReporter. It's green & checked meaning my SSD is "OK". But it's down to 70%. See screenshot.

Is it time to replace the SSD? Philosophically, is sudden death possible...self-combustion?

No, I don't think, unless you drilled your Mac passionately with 24/7 Torrents, file sharing, RAIDs, etc.
Mean that they are pretty tough. And if SSD approaches its end life – usually you would have read-only disk type (so you could reach your data)

But if you worrying about this too much then yeah, buying a spare SSD is not a bad idea

are you often doing heavy reads/writes? If not, then dont overthink stuff. SSD failure does not happen as much as creators of those "check ssd health" apps would like you to think

Just back up your data regularly as you normally would, no matter what the app says.

I too use SSDReporter and while the longevity of SSD's causes doubt, I dont think you have any worries unless your a really heavy user or Crypto Miner, fairly unlikely on a Mac.
This is the read out on my 2015 iMac after I recently replaced the 2TB "Spinning Rust" (makes a great Time Machine) with a 2TB SSD, and here's the result: (see below)
Based on the usage over the last 8 years I have at the very least another 8-10 years left.
Apple will have either gone back to intel by then or there will be another chip to replace Apple silicon lol

Wondering what the OP did to get that much wear on a 2015 MBP SSD?

The SSD on that model IS removable, but you can't get one from Apple (you can find used Apple OEM drives on ebay, etc.), and the 3rd-party "replacements" will use more power and can present other problems.

For means of comparison, I have a 2018 Mini that is now 4+ years old. It was an Apple refurb, too. SSD Reporter (free) says I have a rating of 98-99% (and this Mini gets used a lot).

I will attribute "the lack" of wear to the fact that since it was new, I have disabled virtual memory disk swapping using terminal. I sense that accounts for a LARGE part of the "drive wear" that users seem to be experiencing in recent years on the Mac...
