Now my system is ona WD Velociraptor 10000rpm 250GB (no raid + external
backup).
All relevant (to me) data are on 1TB disk (raid 1 md mirror + external
backup), which holds some /home sub-directories (symlinks), a partition
containing some VM, other partitions...
I am going to replace this mechanical disk with a Samsung 870 EVO 500GB
with a TBW of 400TB and 5y warranty...
Being not sure about durability, I would think about reducing the writes
to the SSD, to minimize the risks of losing data...
That's why I'm asking... understand how much I can *really* trust SSDs

others think it's still preferable to reduce writings... and that's what
confuses me

reduce writings on SSD, if it really served to increase the life of the
disk... here is my doubt

see above... :-)
