Ordered this one because it was recommended in my computer magazine and my old Iomega was becoming very sluggish. It is a real gem. It is a nice neat little drive and 100% silent, I don't have to worry about switching it on and of as it does it in sync with the computer. As a professional. videographer I use it mainly for storing wedding videos and found it faultless.There is also a good backup software that comes with it but as the files I use run into 10's of gig I haven't used it.
