Assuming you used 15.1.10 and the quick/easy installer, the following things have been do increase disk life and performance:

* Enables TRIM and soft updates for better crash recovery (a fix is in 15.1.11 to address setup issues)
* Only one partition to maximise controller flexibility WRT write cycles
* No swap space that might wear down the disk
* Root partition has noatime set to avoid fiddling with the file system

The one thing you can do to increase disk life is go to: System -> Settings -> Misc and enable "Use memory file system for /tmp and /var". After reboot these changes take effect.


Hope that helps,
Franco

yes, i used 15.1.10.
I had been done as your suggestion, and apply remote log server with splunk.

Thank your work!

You are welcome. Exporting the logs is a good idea. :)
