To give you an idea, I have a 24/7 server here, with a 4GB rootfs (ext4, no journal), including /var/log, and gets

writes, according to dumpe2fs. If it were on flash media, that would be about 8 full overwrites. 2992 remaining. Or
to put it another way, it has used up about 0.26% of it's life expectancy so far over 20 months. I would worry far
more about silent bit-rot on traditional RAID mechanical disks.
you really do not need to give me an idea :-)

On how big a file system / disk?
Even if it was a 4GB SSD, you'd still be at 25% of it's life expectancy
after 18 months. That's 6 years of total projected life expectancy. I
have grown to expect less out of my mechanical disks.
