Hey Jon,
Ulrich has it right when he say's you must have a hard drive to utilize the USB Interface Card. The Card is only a means of having direct access to the hard drive on the PSR. Musictronics does offer a package deal for a 5 gig hard drive along with the USBIF Card. I don't believe you will find an easier way to edit, save, transfer or backup files from the comfort of your PC Desk chair.
The ease of use is great. I recently edited and transfered over a thousand karaoke files to the hard drive on the psr. It's no different than working with hard drives onboard your PC. The Drive and any partitions all show up in your windows explorer/MY COMPUTER. The money is well spent if you like editing on the computer or if you want to download files from the internet and save them directly to your PSR. So if you've got the dough this products a go! ... as in GO and get one.
Regards,
