So I build myself a nice FreeNAS server and I'm on the fence on how many drives and how much total storage do I need or isn't an overkill. My server is a Pentium-4XXX Dual Core, Asus Z97-C, 16GB Ram, 120 SSD M.2 (OS), Dual GB Ethernet and 2 PCI-E 6x Sata III cards. I want to mostly have it as a cache server with either Rancher or Docker and have it cache Steam, Origin, UPlay, WSUS, maybe some Torrenting and some backing up of my older external drives. I was thinking of 10x 4TB Reds or 10x 2TB Reds as my final capacity. I won't buy them all at once, start with some and go from there. I don't know if the 40TB is overkill or not but if I can avoid overspending then I would consider lower total capacity and upgrade further down the line.
