I think I'll need a NAS soon. I'm currently using a Mac Mini as a HTPC with a 2TB USB drive attached, but I'm running out of disk space. I could buy another HD, but I'd rather have a single box with a single logical volume.
The only use cases for the time being are to stream media to the Mini and to other computers (though also via the Mini, as I'm using Plex) and of course adding new stuff occasionally.
I'm not sure which one to get, though. A 2-bay NAS with another 2TB drive would last quite some time. But as my collection grows, I get more and more worried about losing it because of hardware failures. So I should rather get a 4-bay NAS with three 2TB in total and use RAID-5, right? According to Synology's RAID calculator, I'd end up with 4TB usable space. That's fine, and I'd still have one free bay.
I had a look at Synology's product lineup, and it seems I have to choose between the
DS413j and the
DS413.
The major difference seems to be that the DS413 has got a 1GHz dual core instead of 1.6GHZ single core, 1GB RAM vs 512MB and USB 3.0 (and the price, of course). How much power and RAM do I actually need? The theoretical maximum demand is two simultanous 1080p streams + one file transfer from/to the NAS, but in reality this will hardly happen.
Another minor question: If I wanted to separate data on a simple physical volume, (e.g. Media + Backups + Work), I'd partition it. How would one do this with a NAS? Simply creating subfolders?
edit: Apparently the DS413 is noisy. I'm gonna compare with older models (DS412 etc.) as well.
