I have an FS, which I think is similar to the 5N.

That initial cost is quite the leap of faith, but dually redundant mismatched drives that I can upgrade seamlessly at my leisure (and if drives ever get cheap again)? Done.
And yes, you could build your own network of rsync shares more cheaply, and performance is frankly unspectacular (may be my crusty 100M network.) But it's a ten minute setup for a virtually inexhaustible file share that you don't ever have to worry about. Sounds about right for our tech-wary OP.
