Windows writes the contents of the working memory to the
hard disk each time you switch to sleep mode and back again as soon as
the PC wakes up. Between 2 and 8 gigabytes of unnecessary data are
written to the hard disk per process! Since SSD hard disks are very fast
anyway, this process is not necessary, but it shortens the life span of
the hard disk enormously.

TBW is the provided SSD rating. This one, for instance, I saw today
sale in the neighborhood of $40 or mo 256G Adata XPG SX850 Sata
SSD. It has an 100TBW. (Unless it was a GIGABYTE UD Pro, I also saw,
neither being stellar in the ratings of a likes of Tom's Hardware.)

So 256 gigabytes over1000 gigabytes for a terabtye written is 256000
divided by 8 gigabytes, SSD Fresh allows, or 4000 sleep cycles. If
you put Windows to sleep once a day, then a SSD with the 100TBW will
last a theoretical 10.9589041096 years before the TBW count is
exceeded and the unit no longer is able to write.

I don't sleep, hibernate or otherwise go green. Or at least I try not
to (my mechanicals are fixed duration in their firmware, at a bare
minimum and necessity, and I haven't yet written a recursive routine
to better, say, read from them at some count just below that firmware
upper allowance).

Although I do define the swap file to a mechanical HDD, which helps
some, I wouldn't, regardless, want to be without platters, not only
for a couple small and dedicated plattered partitions, 8G possibly,
for swap files. I also overprovision SSDs by a smaller factor of
ten-percent, some recommending twenty-five, while others, apparently
exclusive to newer SDDs, are already firmware "over-provisioned".

10.9589041096 years need not be subjectively enormous, exactly, but it
is in principle still about fun time thrashing on your dime, and not
the Operating System's.
