I was reading a thread on unraid on the avsforums and an individual posted and said the write speeds to an unraid server are around 8MB/s or so. Is that true? It does seem awfully low.
 
that sounds about right to me.

I mean its just putting the parity on a single drive so unlike R5 you dont get the striped parity for added speed.
Also the CPU is handling the parity calculation.

Just as slow as using the onboard R5 on an intel mobo, but its just doing it in a different way.

The advantage to Unraid is not the speed, but the ability to use different size drives.
However WHS does the same thing and isnt slow as balls.

Yeah, I have a WHS box now and my write speeds are 50MB/s+. I just couldn't believe that unraid is so slow so I had to ask.

I was looking for another option that would have a single storage pool and allow me to use drives of different sizes while offering some redundency. So far it seems WHS, unraid and flexraid are the only choices.

Flexraid is a good alternative to duplication for WHS.
There are some people that have set it up and works really well.

Only problem is that it suffers from the same fundamental problems as duplication. Its not Real-Time.
Just like duplication it runs on a schedule.
The advantage is that it uses parity instead of full duplication so you get more usable drive space this way.

Your other option is OpenSolaris ZFS pool, but I dont know much about that.
Maybe Unhappy_Mage will drop in. He seems to know ZFS fairly well.
