Samsung Develops SpinPoint M5, MP1 Hard Disk Drives

Samsung Electronics announced its new 160GB hard drive using 2.5" disks. 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. Samsung has already shipped test samples of the SpinPoint M5 Series to OEM vendors and plans to begin mass production in mid-April.

The SpinPoint M5 series utilizes perpendicular magnetic recording (PMR) technology, and the disk drive design has been optimized to allow improved-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 15% quieter and use 5% 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.

The second novelty is the 7200rpm premium 2.5" hard drive, SpinPoint MP1. It provides company's highest storage density of 200GB at 7200rpm on a 2.5inch disk base with SATA interface. The MP1 series is designed for enterprise applications such as workstations, RAID servers, and blade servers.

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.

The SpinPoint MP1 series comes in 80/ 120/ 160/ 200GB capacities with a supporting 8/16MB cache memory. Mass production is scheduled for May, directly following sample availability in early May.
