So im about to pull the trigger on a new Mac Pro. I have just about every apple device except a powerful workstation and an Airport Time Capsule. Currently I use a Windows machine and a NAS with four 4TB HDD in it for file storage and backup. So Im looking to go completely into the apple ecosystem. The Mac Pro I have all figured out on what i want, but im also looking at replacing my NAS. I find my current NAS limiting and am looking for a better solution. After a little bit of research, Its looking like buying a Mac Mini and installing OwnCloud on it might be a viable replacement to my NAS. So that leads me to my next series of questions. 1) What sort of power am I to be looking for in a Mac Mini to act as a host server to OwnCloud? Do i need power or can I keep it cheap and buy a $499 model? 2) I would need to buy some sort of external enclosure for my four 4TB HDD. I would like to start using a RAID setup which means I would probably need a multi-bay enclosure. The Mac Mini has Thunderbolt ports, as well as USB3. From my understanding, no matter what interface I chose to use, the bottleneck will be the mechanical Drive, then the Gigabit ethernet, and last the interface that I Choose. Is this correct? 3) I have never used Time Machine before. I should be able to set my MacBook Pro to backup to the networked Mac Mini whenever it is on the same network, correct? And then when I am on-the-go, It wouldnt back up until I got home. Unless I used a VPN to connect to my home network. 4) Has anyone used GoodSync as a dropbox-like client to access a NAS? I currently use it, and like it fairly well. But I wanted to also see if anyone has any experience with using Goodsync with OwnCloud? Any insight before I make this final jump into the apple ecosystem would be appreciated!
