Current setup has 3 TB hard drives but I have bought several 8 tb hdds that I want to replace the 3tbs with. Question is am I better off to just find a way to transfer all my content off of the current system and just blow out the array and put a new one in, or these days with the ZFS thing should I just avoid having the traditional array at all? Just curious. I am running on basically the same setup that I built like 3 years ago just ready for an update looking for what will give me the best long term results.
