I want to purchase 2 x 2TB drives, and install FreeNas on my Dell Powervault 745N.

People on the internets seem to be having trouble with the MD3000 firmware, and I want to make sure I can solve any issues before buying the drives.

Before I invest, I have 3 questions :

Is there a partition size limit determined by the RAID controller? That is, could I have a striped 4TB partition?
The spec sheets make me wonder if the RAID controller needs all 4 drives in order to work. Is there any reason this will have to run in RAID5?
If I buy 4 matching drives, would the controller support a RAID6 configuration?

I'm basically new to all this RAID stuff - sorry for any noob questions.
