Newbie Question on HDD-configuration

[TheUnexpectedGuest]

Hello,

I'm new to PBS and I have a beginner question: What is the best way to configure the HDD's? I have 3 HDD's and I'd like to configure them in Raidz-1. I have read, that some users install the system itself on a seperate disk and only the backups on the Raidz. But, when I have system and data in RAIDZ and 1 disk is not working anymore I can change the HDD without losing data. When I install system on a different disk and that get broken I have no backup of the system. Is my thinking correct?

It always comes down to what you have or can buy and to find the best compromise

If you don't want to or can buy more drives, then yes, a raidz1 for the system and the datastore will be the best way. If you can spend more on disks, then having 2 smaller disks for the system can help to split up failure domains.
