one thing i noticed recently has got me confused - i have a sata-I motherboard and one of my hard drives failed a few weeks ago so i sent it back to seagate - anyway, that drive was a sataII but had no jumper on it at all - it worked fine but the burst speed was over 200mb/s. I never really thought about it until today as the new drive to replace it does have a jumper on it, which i left at sataI, and the burst speed is less than 150mb/s.
how is it possible that the burst speed of the old drive was higher than 150mb/s if the MB only supports sataI?? - i'm confused.
