Can you set up a raid with three hard drives, could go 4, with each hd having its own operable and useable OS? One hd having windows 7, one with windows 8.1 and one with Ubuntu?

Yes you can create a raid 5 depending on the controller. It is however highly recommended against using raid 5 since one physical failure can destroy the raid. If your main purpose is to install multiple operating systems, I would use one drive per operating system a use a Linux grub boot system to choose between operating systems at boot.

I'm used to configuring server raid controllers for data redundancy and forgot about raid 0 for performance gains. Yes if you configure a raid 0 across 2 or more drives it will be faster. There is risk vs reward though when you use raid 0. The more drives you add the faster the array will be, but the life expectancy (MTBF) of the drives is less. I mentioned putting your operating systems on separate drives for ease of installation, you can do the same thing making multiple partitions across the raid 0. It all depends on the raid controller and the type and size of the drives (drives should match in size and speed for best results). Other members may be able point you to more information on performance raids. Allot of sites come up while searching but I'm not sure where the best info is.
