transfer speed

If I connect up 2 drives in SATA 0, is the data transfer rate the same as if I connect those drives in SATA 1?

I have a Kingston 16Gb 2.0 flashdrive (pendrive). I'm transferring music files (about 9.6GB) and it's taking (according to MSWin7) almost an hour??? Seems something's wrong here(?). I would like to hear input on/about just what 'performance" I should be getting with this equipment...
