Windows 10 lets one mount a CD or DVD ISO image as a drive. Once that

DAEMON Tools to mount a CD for faster access. My question is, do both
methods actually put the data in computer RAM? Or is it temporarily
loaded onto a hard drive? If the latter, is it on the system disk
(C? If it's on the system disk, since mine is a SSD, am I severely
"using up" the life of the SSD?

Mounting an ISO, should not affect the SSD. No writes.

If your SSD came with a "toolkit" program, see if
the toolkit is keeping track of your "gigabytes per day".
It would need to take a reading once a day, to present
that information to you.

The drive keeps a "grand total" of all the writes that
were done. And if the program checks it every 24 hours,
the program can tell you the usage amount per day.
