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 technology, feature an 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.

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 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. With PMG technology, users can fit up to 40.000 MP3 songs and 160 hours of video on a 160GB Drive.

Samsung's newest 2.5-inch drives offer users increased damage risk protection by incorporating free-fall sensors. Many notebook hard drives on the market today have an operating shock tolerance – the amount of shock the drive can take before damage – up to 325G. Samsung's new drives with the free-fall sensor provide 700G of operating shock tolerance. Hard drives enabled with the free-fall sensor are better able to detect changes in acceleration caused by a freefall. The free-fall sensor parks the drive's head on the ramp and turns the hard drive off, protecting it from damage caused in a fall. This offers a dramatic increase in reliability and resistance to hard drive damage caused in the event of a fall.

Samsung's free-fall sensors are located on the hard drive, not the notebook's motherboard. The added benefits of this on-board integration include faster response time in the event of all fall, an improvement in the quality of fall detection, and a smaller minimum fall detection rate of just 30cm. 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 5.400 rpm spindle speed. The new hard drives provide high shock protection capability through an advanced mechanical platform and able-bodied cover design engineered to minimize the intensity of external shock transmitted to the most critical components of the drive.

Samsung's latest 2.5-inch hard drive offers are equipped with the company's Hybrid Latch System, a new latch mechanism that eliminates unpleasant rattling noises and significantly reduces the clicking noise generated when a drive moves its heads on and off the disk according to the operating modes. Also, the drive uses a Fluid Dynamic Bearing motor.

The M80 SATA Series and M80 Series feature 80GB formatted capacity per disk, Fluid Dynamic Bearing Spindle motor technology, ATA SMART feature set, ATA Automatic Acoustic Management, ATA Device Configuration overlay and Multi-Burst On-The-Fly Error Correction. Utilizing Samsung's SilentSeek technology, the drives provide are among the quietest in the industry today.
