DQT (Drive Quiet Technology) - now, this is a biggie. A hard drive can be a noisy fellow in a silent room and surely one spinning at 7200rpm can’t be an exception. But since after IMB labs started talking about FDB (Fluid Dynamic Bearing), noise has been in the target of manufacturer’s research teams. This technology is meant to reduce the overall noise emitted by a drive, both in idle and search mode. Basically what Maxtor did is they removed the ball bearing for the rotating platters and used some very viscous fluid instead. This eliminates points of contact and friction, reducing the noise. One more advantage is that at the same time they removed some moving pasts, subject to consumption and failure.
