nothing special just the marvel yukon on my asus board and whatever the old am2 board has.
The thing is although the USB drive copied back to the drive @ around 17 /18 MBps it only wrote to the disk @ around 11 . Across the network I got a steady 11 MBps basically meaning it was purely quicker because I didnt have to do it twice.
Ive never liked USB drives and it is only a standard ide 2.5" drive most likely 4200 rpm so a sata would be quicker but I doubt it will be that much faster to actually beat the test although it may. I tried it with a kingston pen drive and copying from that was of but to it was awful ( I didnt expect good results)
The USB speed rate imo is bobbins
Over the 80 gig there would have been about 20 minutes difference
