"All of the drives reviewed here are suitable for low noise PC systems. The Barracuda IV and Samsung models are nearly ideal, and the Hitachi models more challenging to silence -- but not impossible. All have their place in the silent PC enthusiast's repertoire of components"
something you need to be aware of is that compared to some other drives, the seagate barracuda's can be a little slow ( i hope that doesnt upset any seagate fans).
The reason I say this is because I went out and bought the cheapest Dell I could a few months ago in order to setup my HTPC. It came with a 40GBseagate, today I ghosted it to a 250GB maxtor (cant think of the model) but it breathed new life and fast new life into it....With the pc on and performing a defrag, i could hardly hear the hdd going...admittadly...louder than the seagate
Yeah I agree on the Maxtor stuff too however they do have specific PVR drives which are ultra quiet. They used to only OEM these but now they are available at different PC hardware stores...
