Unraid’s “killer feature” is the ability to mix and match disparate drive sizes and only requiring the parity drive to be at least as large as your largest data disk, a la MergeFS/Snapraid. Also ZFS chugging RAM like there’s no tomorrow so not really an option for underpowered devices like some NASes. But yeah, TrueNAS is nice.
Thats is a very budget-friendly choice for UnRAID to accept varying drive sizes. As a backup destination, especially a cold backup, the RAM requirements of ZFS should be less impactful. I had lots of use from my TrueNAS box with 16GB, and my dedicated cold backup build is just 8GB on 5x1TB WD Blue (gasp!) HDDs. I always wanted to try other NAS platforms, but I’m away from all my tech for a few years.
