It's more a case that many of us BELIEVE the "dire warnings" about running an SSD "too full" as a system drive.
I'll always believe the dire warnings because in my line of work I MUST assume the worst, to do anything else puts the system installation at risk.
The only thing more important than preserving the system is preserving data, dut as of yet, we don't use SSD's for active data drives.
a longer NAND write life might not be necissary, but relatively
speaking SSD's are "new" "Hard drives have been around for
nearly 60 years. Granted the 1950's versions were the
size of a commercial washing machine, but the basic idea
I say again SSD's are new and the early ones... in the dark distant past of FIVE years ago haven't been around long enough for any of us to entirely "trust" them.
To be honest the fact that I maintained a minimum of TWO backups of hard drives
should indicate that I never actually trusted them either...
If you've ever had an optical disc you burned to backup data that would not read at all or would only read in one specific optical drivr... and you still trust optical backups you probably also believe in Unicorns.
The motto I must live by is "In Redundancy We Trust"
