I would get something like a pair of <A HREF="http://www.seagate.com/cda/products/discsales/marketing/detail/0,1081,630,00.html" target="_new"> Barracuda 7200.8 SATA NCQ (ST3400832AS) </A>- 400GB w/8-Mbyte buffer 7,200 RPM, a 8-ms average latency and a 5-year warranty.
and I would run them as boot drive and data drive instead of RAID 0.
These are plenty fast enough to play video up to full drive capacity.
