Its very interesting that you bring this up.

Doesn't the ProRaid enclosure handle the RAID aspect entirely in hardware ?
I understand that it will run from USB3.0 or SINGLE CHANNEL eSATA and thus I
assume the drive(s) in it look like one big storage volume, when in fact
they are a RAIDed storage device.  That was one of the appeals of it to me.

Some of the other 4 bay RAID enclosures require either 4 SATA connections or
a multiple channel SATA card/cable.  The ProRAID doesn't.

This is the MB I was intent on using.

http://usa.asus.com/Motherboards/Intel_Socket_1155/P8H67M_PROCSM/

It has

*Intel® H67(B3) Express Chipset*
2 xSATA 6.0 Gb/s ports (gray)
4 xSATA 3.0 Gb/s ports (blue)
Intel Rapid Storage Technology Support RAID 0,1,5,10

The RAID options are set in BIOS.

That would be a totally hardware based RAID, right ?

I'm not sure what to say.  I haven't had a HD fail in the last 10 years.
I'm not sure why I would need a RAID setup that would tolerate multiple
drive failures.

What would the multiple drive failure tolerant RAID be ?  RAID 1 ?

Wireframe storage shelves.  That is where my satellite receivers, HD PVR
boxes, networking devices, nas server , asterisk server and hardware and
zoneminder server are located.

I'll probably use the same hardware for the zoneminder server as the myth
server.
