Are USB 2.0 and USB-High speed the same? I have a 200GB file I need to transfer to another system. It crawls over the network so I got a USB portable HD hoping it would be faster. I have it connected to a HP proliant DL380 G4 and was curiour to know if I need to get a PCI USB interface card to get a faster transfer rate. Right now it take about 20 hr to copy the file.
