If like me you mod lots of original Xbox consoles for friends and family and fit 1 and 2tb drives it can be very time consuming to copy on content and set them up, this just makes things easier. Of note with the correct sata to ide adaptor you can use a modern sata drive in the Xbox just nothing over 2TB it is hard to get ide drives reasonably priced these days. If you are copying on a few files sure ftp is the way to go but if you are copying on coinops mega pack for example and a few movies it can take hours to do this will be way better. The thing is FATXplorer is able to mount the drive in windows like any other usb and as you can imagine it transfers at sata speeds for me where good old ftp on the Xbox at best case is 11mbps with the ftp overhead on top of that.
