I think the following questions would be answered with a "recommended hardware for common features" section on that first post?
Are there features that will be limited if a 16gb SSD is used? I have a spare Optane m.2 kicking around.
I'm not a server nerd, as most Hex OS users are likely to be, but does caching and/or journalling go on the boot SSD, or is that another drive again?
I have some familiarity with Unraid running on a USB, so any SSDs in the system are fair game for storage, and excess storage on the boot drive has been useless for my purposes.
