Once I actually get the arrays setup and connected I will try a DD (I am testing on two servers that are older and much slower than the ones we are going to put into production as our xen hosts) and let you know if the final average speed.

Keep in mind that dd is fine for testing raw sequential i/o but that almost nothing in the real world works this way. (How often do you say to yourself "well, I need to go ahead and create an empty 16GB file?")
