If you run Boot Camp this thing is a gem.<br><br>Since Windows uses NTFS, which OSX can't read, it can be a pain the rear end to efficiently get files from your OSX drives to your Boot Camp drive. Sure, you can use CDs, flash drives, or networking to do it (previously I opened it up in Parallels and dragged files across) but its still slower than if it were available to OSX directly. <br><br>NTFS-3G makes that happen. Nice.<br><br>
