Okay, after much thought about what kind of storage solution to get, I think I'm finally sure. I want a Synology DS414. What I understand this is a pretty popular NAS for Mac users, so I have a few questions. 1. Is it QUIET? I will have it in my living room so it needs to be veeeeeeeery quiet, like 1 or 2 on a 10 point scale of audibility. 2. If I enable the mac file service (http://www.synology.com/en-global/support/tutorials/563) can I drag and drop files to the NAS, from my Macbook pro over wifi? And can I just playback video files directly from finder, just like with an directly connected USB-disk? 3. How does the time machine work? Do I need to use the native NAS time machine (how is that performing btw?) or can I use my NAS as a storage medium and have my Mac mini (which will be connected via USB 3 or ethernet if that works) do the backing up? 4. Any other tips regarding this device? 5. If I have four disks, can I have "dual Raid 1"? I mean D2 mirror D1 and D4 mirror D3, separately? BONUS (DUMB) QUESTION: Can I have the NAS inside a cupboard (roughly double the size of the NAS) or would that be suicide heat-wise?
