Preserving SSD Life

Super nerds will say "Modern SSDs will last 17000tb+ / 51 years" - don't waste your time etc etc.

Bugs happen, runaway processes happen - so if it's easy enough to preserve gigs of bits over the lifespan of an SSD, why not? Certainly not something I'd prioritize necessarily (I didn't tweak mine until after it was a year or so old).

Some of my configs are a bit splintered for organizational purposes, so I'll link to those:

Firefox/Waterfox tweaks

• about:config changes

Linux tweaks

• Moving logs to another partition

Disabling timestamp read writes

Disables accessed times on files and folders when you right-click. Access times will be 'frozen' after setting these flags. I find them only really useful in a server setting, not on desktop. In /etc/fstab:

• Pre-pend noatime,nodiratime to all mounted directories (ignoring swap), like so:

# <file system> <mount point>   <type>  <options>       <dump>  <pass>
...
#before:
#UUID=... /               ext4    noatime,nodiratime,errors=remount-ro 0       1

#after:
UUID=... /               ext4    noatime,nodiratime,errors=remount-ro 0       1
...
