I won’t have any important data on this system. Basically my entire physical movie collection ripped into hdds and I will keep the actual physical media. In case of a drive failure, I will have to rip the entire collection again. It would take me so many hours to do it again but at least I have some sort of a back up.
Pretty much, I need a lot of space, decent speed and relatively moderate reliability.
To increase reliability, I can consider SW Raid 5 or add a Raid controller and 2 additional drives for Raid 10 (8x 12 TB total). Both options I lose disc space.
