UnRaid community seems to be very big, same with TrueNas. Also, not sure if UnRaid includes any kind of customer support with the paid license.īased on what I gather UnRaid system requirements seem to be more forgiving than TrueNas.

Not sure if those options have the ability to mix and match different sizes of HDs though like mentioned above. Yeah, there is TrueNas Core (FreeBSD), TrueNas Scale (Linux), and Open Media Vault (Linux/Debian), which are free. Not sure if Unraid is better at this price. OpenMediaVault is an alternative which is free.
