I run 2 G-Techs on an HP 4200. Both run very fast! I have the G-SATA that comes with it’s own controler card (you may have trouble getting 1, I am on a list at my dealer- I hear there is a problem geting the cards from the vendor)
The other drive in FW800 drive. The firewire 800 card is only $50 & there is no conflicts with MoJo being on the FW400 port.
