The MP1 series is designed for enterprise applications such as workstations, RAID servers, and blade servers while M5 Series has been developed specifically for portable consumer electronics, where the key to success lies in controlling noise, vibration and power consumption.
The SpinPoint MP1 Series utilize perpendicular magnetic recording (PMR), a serial ATA 3.0 Gbps interface, and feature native command queuing (NCQ) for high performance. To protect the disk drive from vibration and shock, a rotary vibration controller (RVC) and an optional digital free-fall sensor (FFS) have been implemented.
The RVC technology, first applied to the SpinPoint MP1 series, prevents the head from leaving the track under severe vibration conditions, thereby reinforcing data reliability.
With the industry's highest maximum-density-per-disk at 100GB in the 7200 rpm class 2.5" drives, the SpinPoint MP1 series comes in 80/ 120/ 160/ 200GB capacities with a supporting 8/16MB cache memory.
The SpinPoint M5 series utilizes same 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.
Capacity of the single-disk platform ranges between 60 and 160GB, while a dual-disk model is under development that will provide up to 250GB of storage space. The 250GB model to follow will greatly expand the storage capacity of mobile products, in step with the surging growth of multimedia content and the rapidly changing mobile environment. The weight of the 160GB hard drive has also been reduced by approximately 4% from 98.66g to 94.83g, helping manufacturers to lighten their finished products. SpinPoint M5 hard drives are fifteen-percent quieter and use five-percent less energy than other models with the same storage capacity.
The new SpinPoint M5 hard drives feature a 5,400rpm spin rate, 1.5Gbps SATA interface and 8MB cache memory. PATA models will be added to the lineup in May.
