This is my third HDD in 5 years and is designed to give back up to a Vista PC with a Western Digital Mybook already doing the same for another PC.
First of all, it comes fully protected in a stout box with protective film over its glossy black finish. Sits flat on 4 rubber feet unlike the Mybook that is expected to sit upright. I have also used the Seagate upright and it seemed quite happy though. Glossy black finish may not be the best to avoid showing fingermarks but then, how often will you move your HDD?
The Seagate is simplicity itself to set up. Attach the mains cord (it uses a mains adaptor that has two or three pin adaptors which are very easy to switch) and then fit the USB lead and off you go. It launches the registration form in which you only have to add your contact details and it is then ready to us. No formatting needed on a Windows machine, you can drag and drop files straight away.
Very quiet (quieter than my Mybook), it has a green light that is initially on to show power on and then flashes during file transfer. Not as funky as the Mybook twin flashing blue bars but does that matter? Down to personal choice.
File transfer is as good as the Mybook and I have found no heat build up to speak of.Power efficient,it has the excellent Seagate reputation so hopefully durability won't be an issue. This unit is also smaller than I expected, has a quality finish and will sit discretely on any desk.
So, given the proviso that I would always recommend that, before buying, potential buyers check dimensions and finish of any peripherals that are intended to remain visible (assessment of appearance is such a personal consideration) , I would have to say that I prefer this unit to my 8 month old Mybook and as it also represents excellent value for money, happily give it 5/5 and an unequivocal recommendation.
