As it is, the system is much slower, but still usable. The nvidia software will allow me to hot swap the new drives, all i gotta do is plug each one in and let the software do the rest.

Are sure you don't mean Raid 1? If one disk in a Raid 0 array fails you loose everything since the data is split between the two drives. Don't think I clarified this, but Raid 5 is only for the data,
not the OS. The OS drive should be fast (depending on its use) I would put a raptor 10k drive in there, if I was really worried about it failing I'd mirror it with another same size drive in a Raid 1 configuration.
1 250gb 10k raptor drive is going to smoke a pair of 1 TB drives in a Raid 0 configuration. My OS drive (be it my server or my desktop) is always the fastest drive in terms of IO, all my data is kept on the Raid 5 array and just accessed via mapped drives. It's cheaper and easier to keep adding more 500gb drives to the Raid array when I need more space, put the new drive in the carriage and turn it on; expand the array and wait for it to re-write the parity and I'm good to go. Long as 2 drives don't fail simultaneously or consecutively my data is quite safe. Keep in mind my Raid array
only has data on it.
