I Guys,   I'm running a Gen8 equpped with 2x3TB WD RED + 8 Gb RAM since last year. Only used as a NAS with Freenas. I'm a noob, without any *nix knowlage. The disks are running in mirror-0/RAID 1 setup ATM.   Now I want to expand the use of the server, for CCTV. I haven't yet decided if I just want to dump captured data on the NAS or run a NVR software and dump the data aswell.   I was thinking following config: 1st set of HDD = 2x3TB in mirror-0, pure NAS
