Hello, I have the sy-pex400032 with the drivers from the product webpage. The reason for this message is to request help with slow transfer speeds. Since this is a 1x card, will my M4 RAID 0 always have test scores like this? Youtube videos show two M4 RAID 0 drives reaching much higher http://www.youtube.com/watch?v=WuescKED8qA        http://www.youtube.com/watch?NR=1&feature=endscreen&v=S5ZrBM_EPC8
