So the SSD usage is no issue ?
No one can say for sure - not even Internet pundits.
Your personal choice whether to buy one.
However, look at that table again. SSD life-span is usually specified as data
written. Even when no longer writable the data is readable.
In the above example the user ran for 191 hours, power-cycling 256 times (sorry, don't get that and 256 is too much like a byte quantity). During this time they wrote 15.7 Terrabytes of data. Not MB, not GB, but TB. (What?!) That apparently used up 1% life. Okay, if true that equals 1500TB write life-expectancy.
Official figures suggest the TBW (terrabytes written) life of a 256GB SSD is between 60 and 150 TB depending on who you listen to. I believe Samsung claim the higher figure for their top models.
So what is so wrong with the figure the complaining poster is suggesting? It seems 10x the usual expected life span. Sounds fine to me.
But again it is a choice thing. People do not think twice about a $1000 phone and changing it every few years.
