On the subject of vibrations when using multiple drives in a case (tower), I'm using silicone grommets on all the drive screws to isolate vibrations. This does seem to greatly reduce the vibrations reaching the chassis, and makes the machine a lot quieter, and so I would expect that this minimises the vibrations transferred between drives via the chassis. In turn I would expect that this greatly reduces errors related to high vibration levels when reading and writing: less vertical head movement, leading to less variation in write signal strength.
