The Spin Point M5 series utilizes perpendicular magnetic recording (PMR) technology, & 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 & power consumption. Samsungs Spin Point M5 hard drives are fifteen-percent quieter & use five-percent less energy than other models with the same storage capacity.
