The SpinPoint M5 series utilizes perpendicular magnetic recording (PMR) technology, and the disk drive design has been optimized to allow ultra-precision adjustment of the head parking ramp position for high-density recording. The M5 Series has been developed specifically for portable consumer electronics, where the key to success lies in controlling noise, vibration and power consumption. Samsung's SpinPoint M5 hard drives are fifteen-percent quieter and use five-percent less energy than other models with the same storage capacity. The low-noise, low-power features are attractive to notebook PC or tablet PCs users.
