First, you should have bought enclosures with included RAID controllers, 
then you'd be finished already.

But then, I guess you wanted to save the money, but at least go get some 
real hardware RAID controller. Look at Areca ( http://www.areca.com.tw ) 
if you use Linux or Windows, the 1680 series SAS controllers can cope 
with SAS/SATA drives, up to 128 drives per controller. You can put a 
cache up to 4GB on the controller, and a battery backup module that 
protects your data in case of power outages. Those controllers are 
blazing fast, have good admin tools, send you an e-mail in case of 
problems, and they used it in the video that Chris mentioned:

In the end you see they used an Areca 16port, plus an Adaptec 8port (I 
guess because they only had the Areca in 16port available).

Then configure a RAID-60 or whatever you like.
