I decided it's time to upgrade to a NAS so I've been doing some research. Initially, I thought about getting the LaCie Network Space Max. The reviews are mixed but the price was right. But can you put a price on keeping your data safe? So then I thought about buying either a QNAP or Synology NAS. From the posts & articles I've read/researched, it's mostly subjective but many like the Synology NAS, which I did too. Now, since I'm new to the world of NAS, I really wasn't sure if I need the 1 bay or 2 bay model of the Synology DiskStation, DS110j vs DS211j. This is for my home network so do I really need RAID? It's mostly to store my media files, backup my MBP, store torrents, remote access, etc. If I get the single bay, is it easy enough to upgrade/expand to a multi-bay later and just copy the files over? Or should I just save a little more and the the 2 bay now? I was looking at the WD Caviar Black 1.5GB HDD to put inside it. It seems to be reliable. Thoughts? Your advice is greatly appreciated.
