You do not need read/write 800MB/s Disc IO for home media purposes.

It all depends on your needs/wants/desires/funding. Some guys love absolute performance, and I'm that way about my gaming performance, but I still keep a very tight budget. I use volt mods, and overclocking to push that to the limit on cheaper hardware.
For me, the media server only drives my PC's & Home Theater...a 95" projector & Paradigm speaker system. That is in the living room and our main screen. The only other TV is a little 13" in my sons room. Then we have me & my wife's PC's. I do plan on getting a TV for our bedroom eventually, but we really don't need it. My point is I'll never be serving more than 3 devices at a time. The transfer rate of 1 drive is plenty for that. And these WD 640GB drives I have can move data pretty quick. unRAID is perfect for me in this regard. The drives will do 100MB/s for the most part...that's 800Mb/s and enough to pretty much efficiently use a cheap Gb ethernet setup.
I love bang:buck. For $400 I have an excellent solution that serves my needs well. As-is I can add up to 8 drives, and w/ a cheap 8-port RAID card i can max out my unRAID setup. I doubt I'll ever have to go above 8 drives...I think HDD capacity will increase fast enough to keep up w/ my storage needs.

I would say that an acceptable minimum for home RAID is single hard drive and gig ethernet speeds, say, 120 MB/sec or better.
The 20MB/s is write only, and due to parity calculation. You can alleviate this by using a cache drive which limits write speeds to the speed of 1 HDD.
120MB/s (960Mb/s) is enough to saturate Gb ethernet, and might be appropriate if you have enough simultaneous users. For me 90-100MB/s is more than enough.

unRAID excels at allowing you to use a bunch of drives in a protected manner.
As long as your parity drive is amoung the largest, the rest of the drives can be of any size. It's perfect for a read mostly media server.
Yep, it fit my needs as well. I do want extra features, and it looks like it will be difficult to implement some of the extra features I want to have, but I've read its possible. I want print server functionality, and it is possible, but it will take some time to figure out. Also, I want to get the VMware running w/ Windows virtual so I can torrent ( I guess I could get the print server through the virtual machine to kill 2 birds w/ 1 stone). Agian, it will take some time to figure out.
I like a challenge, so this has become a project. Any advice you guys can give (I'm looking at you WeeboTech
) would be greatly appreciated.

Really? I didn't know that.

I didn't think so...

Wow! Butters was right. I didn't know that and I've been playing w/ Matrix for a while. If I had known this earlier I might have given it a whirl. My experience w/ RAID5 and RAID10 on ICH9R was overall positive, but I did have a quite few rebuilds that kind of annoyed me. At the time the drives were all in my gaming/HTPC/storage rig, and it wasn't an ideal setup having it all-in-one. The extra drives created a lot of extra heat I didn't need, and they were spun-up all the time drawing more power. Plus, having a machine running near the ragged edge of performance is not ideal for RAID stability.
On a dedicated machine, though, this could be a pretty viable solution. I still don't like the reliability of the Matrix RAID 5, though. Don't get me wrong, it is decent, especially if you have a dedicated PC [CPU], but I just don't feel the speed advantages outweigh the added redundancy that unRAID provides. On the other hand, you can run a Windows platform, and implement additional features more easily...it really depends o your level of tweakism.

Getting an intel motherboard, Intel CPU, and selling your current equipment would still be much cheaper than an expensive RAID card.
