Low Noise external drive?

[AT0MAC]

I currently have an old G-Drive Mobile with FireWire 800/400 & USB2.0 as my TimeMachine backup.

Problem is that I not long ago upgraded it from 320GB to 500GB and the new drive make quite a lot of noise...
Not actual noise to be worried about, just buzzing that gets pretty annoying whenever it is doing it's thing.

Also it's occupying the only FW800 port I have, bit problematic as I have another FW800 drive I also want to access from time to time...


That's why I am now looking for a more low noise drive that can daisy chain FW800!!

Have been looking at the WD Passport Studio (the black one) or the Lacie d2 Quadra - wich one is the most low noise or is there any better?



It can not be taller than my Mac Mini as it have to fit in next to it in a Sonnet MacRack mini mount.
