re: Best NAS for small business/home

If you're more technically inclined, I'd go the build-your-own route, especially if you have spare parts laying around. You'll need to know a little more than your average user, but you can do it for much cheaper and have a lot more flexibility over your setup.

I currently have a Buffalo TeraStation NAS and while it's done great for me (actually bought it for like $200 used on eBay about 2 years ago, with 4x1TB drives), I decided to consolidate all of my various computer hardware hardware into one FreeBSD server (running vanilla FreeBSD 10.3).

This box is now my firewall, router, SMB/AFP (with Time Machine) server, Plex server, etc.

I haven't fully gotten the network storage up though, when I get my next paycheck I'm gonna go with 4x4TB HDDs and put them in a RAID-Z1 (RAID5 on ZFS) and migrate all the data from the TeraStation and some various external hard drives I have laying around.

Just be sure that if you do build your own setup, you use hard drives that have firmware specifically designed for NAS applications.
