It is transparent.  A RAID controller presents a PHYSICAL device to the host operating system, that is actually a logical device. your host computer has no idea RAID is involved.  Jut format it any way you want to.  

The killers are ...
1) Performance and the "correct" or optimal arrangement is a function of numerous variables, but then you have the same issue when dealing with a system that has multiple devices with various performance and reliability characteristics..

2) You can get in trouble with max config . Most BIOS's & windows operating systems won't boot a "Disk", whether logical or physical which is > 2.09TB.  

So there is no best software.  Your O/S & bios will only see whatever the RAID controller presents to the computer.  Pretend they are physical disk drives and you will be fine.

Just being picky:  :-)
 "A RAID controller presents a PHYSICAL device"
or
 "A RAID controller presents what looks like a PHYSICAL device"

Otherwise i agree with dlethe, As far as your OS is concerned it just sees a disk of unusual dimensions (size)
