Take this from someone running 3PB of physical disk on a deduplicated backup environment, all on FC disk.
NAS has a place. NAS can be a fit, depending on performance expectations. If you looking to push 1GB/s sustained for 500 users, a NAS server with 4 spindles is not the right fit to meet those expectations. It will fit for an environment where you have 2 - 3 users, and need 5 - 10 MB/s.
For my home environmnet I use a QNAP ts-409pro, with 4X1TB drives in a RAID-5 config. I have a couple 750GB drives that I use to backup important data (some data is disposable). Local backups I just mir the data using robocopy. I use truecopy to encrypt a drive before using robocopy to mirror the data, then pass the data for a friend to store the drive in his safe 35 miles away.
I also have a 1tb drive in a raid-nothing config on the back of the TS-409pro, that I backup my desktops to, using Acronis. I dont keep data on my desktop, so it is mostly for just having the desktop image...
The TS-409 is a fully functioning server. It might have a slower processor, but mine has been rock solid for almost 6 months now. It does www, nfs, mysql, native ssh access, perl, windows AD, ftp, RAID-0, RAID-1, RAID-5, RAID-6, JBOD, hot-swap drives, drive upgrades (replacing 500GB, upgrading to 750GB / 1TB drives),etc, etc.
RAID-10 is overkill for the home environment. Buy a USB drive, and back your crap up once a month.
