Pi SD + USB vs USB Boot only?

@HarvsG

How do you do this?

Well, back in the day armbian just did this for me by default

• commit=600 to flush data to the disk every 10 minutes (/etc/fstab)

But meanwhile the situation also improved a bit for HaOS.

Researching I/O Write Improvements

Hello, After having some discussion with @orange-assistant in the Home Assistant OS 8 release thread I started doing some I/O write improvements research. Let’s discuss the results in this new thread. The main goal is to find if ext4 commit intervals, tuned VM dirty writeback timeouts (vm.dirty_expire_centisecs) and potential other tunables can have a positive effect on writes. The goal is to essentially cause fewer writes to the storage, which should lessen the write amplification effect typi…

Now the commit interval is not the default (from the hard disk stone age) of 5 seconds but 30 instead.

If you really want your cheap flash cells to last long just install supervised and set the commit interval at the OS level to an insane high value Or probably not anymore

@bdraco

Statistics runs need the data committed before they can run which means the every 5 minutes stats generation will always trigger a commit. A commit interval larger than 5 minutes makes no sense with the current design.

that was different back in the days (no long term statistics at all ) when I had HA running on a $10 SBC

I use a Orange Pi One Quad-Core H3 with 512MB RAM running the latest Armbian with Home Assistant via Python Virtual Env environment. I catched the hardware for $9.99 from ali express.
