Samsung powers up 2.5-Inch hard disk drives featuring PMR technology

Samsung ratchets up the strength of its 2.5-inch hard disk drive offerings for notebook and enterprise computing applications with the introduction of the new M80 SATA Series and M80 Series. Both series utilize advanced Perpendicular Magnetic Recording (PMR) technology, feature optional free-fall sensors and offer increased storage capacity, now up to 160GB. The M80 SATA Series features the 80GB HM080HI, the 120GB HM120II and 160GB HM160JI. The M80 Series includes the 80GB HM080HC, the 120GB HM120IC and the 160GB HM160JC(1).

 

The M80 SATA Series and M80 Series are Samsung’s first hard drives based on PMR technology. Unlike traditional longitudinal recording technology, which lays data bits end to end where they can flip and corrupt data on the disc, PMR technology places the data bits perpendicular to the disc, which should reduce the corruption factor. In addition, by placing the data bits standing on end, more data can fit onto a disc, allowing for greater storage capacity.

Targeted for mobile computing needs as well as enterprise applications, the M80 SATA Series and M80 Series feature a 8MB of onboard data cache and 5,400rpm spindle speed. The new hard drives provide shock protection capability through an advanced mechanical platform and able-bodied cover design engineered to minimize the intensity of external shock.
