Should i get one 300 gb SATA or two 200 gb SATA?

I am building a new computer.

Asus P5AD2-E Premium
Intel 3.2 or 3.4 ( not decided yet)

I have a real problem here. i like to use this new set up for mainly video editing. I have some old VCR taped that I like to transfer to DVD. it takes about a little less than 250 gig for a 2 hours tape to be transferred to the hard drive , and then burn it to DVD. Now, if i get just one HDD ( which I like to get the Seagate barracuda 300 SATA) it probably will be connected to the regular SATA connector, right? I like to know if i connect two 200 or 250 gig through RAID SATA, would some of my videos be on one drive and the rest on the other one? and if this is true, when I am burning, the videos from both drives will be burned continuously ? I really like to have one big drive so I don’t have to mess with all that RAID stuff.

Thanks a lot for the help.

Never buy the Seagate Barracuda 7200.8 SATA drive. :mad: I was given this advice by my friend and i dint follow n look at my condition my disk doesn't work for 2 months in a stretch without failure.. I have already got it replaced 4 times and lost 60 dollars... Now going to consumer court.. They are the worst people.. And u can imagine my anger by looking at the name. :mad:
 
If you choose two SATAs they don't need to be raided.

My Segate SATA has been running perfectly for a year now being used for several hours on a daily basis.
