I have a mac pro (2012) with 4 Western Digital Caviar Black's and 1 OCZ Vector 150 SSD. In the same room I have have two KRK Rockit 6's and 1 KRK 10s Sub. Even with foam everywhere there I can still feel vibrations off the computer. How bad is this for the hard drives? I am really worrying about this. The subwoofer is on a load of polystyrene, the two monitors are on Universal acoustics foam pads, and the mac pro is on a load of polystyrene too. I really need advice on this!
