Which hard drive is more quiet?

[Mercuric Oxide]

I'm looking into getting a 500 GB HDD for my MP, either seagate barracuda, or WD Caviar. Anyone have experience with the noise level?

Thanks

Anyone have experience with the "Hitachi HUA721050KLA330 Ultrastar A7K1000" (500GB 32MB Cache)? How noisy is this drive?

Western Digital are quieter than Seagate now I believe. The quietest drives are samsung spinpoints and are generally regarded by silentpc enthusiasts as the ones to go for these days.
