K listen there are a lot of factors affecting your speed, and it basically boils down to NIC(network card) speed, network cable, hard drive speed. Like if your NIC can support 100mb Full Duplex Transfers, You should have no trouble transferring at full speed, But I think your hard drive can only write so fast like 1.5MB a sec is great still, dont expect to get the same 10MB+ transfers like when you are downloading from the XBOX. In short only some people with certain drives can attain these speeds. As well all factors must be set to standard if you wish to even hit those transfer speeds.
