Until now, two disks were required to reach a 60GB storage capacity in a 1.8-inch drive, which increased the height and size of the drive. Samsung's N-series utilizes perpendicular magnetic recording (PMR) technology to offer 60GBs on a single disk. As a result, Samsung is the first to offer a 60GB solution in the slimmest available 5-millimeter form factor. This makes the drive ideal for use in small portable media centers and mobile music devices.
"Samsung is offering cutting-edge technology from an aerial density standpoint with the new 1.8-inch N-series. Given the same amount of hard drive space, Samsung is able to offer 60GB per disk where our competitors can only offer 40GB," comments Albert Kim, national sales manager, Storage Systems for Samsung Semiconductor. "This enables us to produce more compact hard drives that will fit into smaller, more portable electronic devices."
N-series drives are very quiet with just 1.8 Bel, a measurement of sound. As the sound level detectable by the human ear is 2 Bel, this makes the operating sound of the new drives undetectable to the human ear. In addition, the N-series features ultra-low power consumption that is just .3 watts in low power idle.
Hard drives utilize PMR technology to achieve such a high level of storage capacity per disk. 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 reduces 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.
Other features are an ultra low power mobile SoC, a quiet and robust platform design, fast drive ready time, high efficient hybrid latch system, shock sensor and free fall sensor which is optional. All are equipped with a 4,200-rpm spindle speed, and 7.14-millisecond average seek time and a 2MB data buffer.
