Strengthening its position in the growing notebook hard drive market, Seagate has announced it is currently shipping a 250GB Momentus 5400.4 notebook drive that delivers a compelling combination of capacity, performance and durability for mobile computing.

The new Momentus 5400.4 hard drive is part of the world's most innovative family of notebook drives that includes the Momentus 5400 FDE.2 hard drive, the industry's first notebook HDD with built-in encryption and currently the most powerful security solution for mobile computing, Momentus 7200.2, a super-speedy 7200-rpm notebook drive with free-fall protection for extra durability; Momentus 5400 PSD, a hybrid hard drive that combines disc storage with flash memory to reduce power consumption in half, boost performance and enhance reliability, and Seagate's flagship Momentus 5400.3, a 160GB 2.5-inch drive and the world's first to use capacity-boosting perpendicular recording technology.

Independent research firm IDC puts Seagate's worldwide share for 2.5-inch notebook PC and PC-related hard drives for the first three quarters of calendar 2007 at 19%, a share that elevated Seagate to the number two spot.

"In the five years that Seagate has offered hard drives for notebook PCs, it has become a contender for the notebook market share crown," said John Rydning, research manager for hard disk drives at IDC. "Seagate's product breadth and customer responsiveness have contributed significantly to the company's ascent in this market."

As explosive growth of notebook PCs continues, more users want the power of desktop computing - high capacity, screaming performance and rock-hard shock resistance - on-the-go. The new Seagate Momentus 5400.4 hard drives deliver just that, using second-generation perpendicular magnetic recording (PMR) technology to deliver up to 250GB of capacity and impressive performance on the strength of a high speed Serial ATA 3.0 Gbit/second interface. Seagate's newest Momentus hard drive is also tough as nails, delivering industry-leading operating and non-operating shock specs of 325 Gs and 900 Gs, respectively, ideal for systems that are subject to rough handling or high levels of vibration.

"Personal computing is the core of the digital experience as users continue to use their PCs as the hub for storing, sharing, syncing and protecting their digital content," said Michael Wingert, general manager of Seagate's Personal Compute business. "Seagate is pleased to be at the forefront in enabling mobile computing that gives business users and consumers the freedom they need to bring the digital world to their fingertips."

The Momentus 5400.4 hard drive is perfect for mainstream laptops, performance-hungry gaming systems, workstations and personal external storage. The 2.5-inch, 5400-rpm giant features 250GB of capacity on just two disc platters and, like the rest of the Momentus series, is lean on power consumption, allowing notebook users to work longer between battery charges. And the drive is virtually inaudible thanks to Seagate's innovative SoftSonic fluid-dynamic bearing motors and QuietStep ramp load technology.

The Momentus 5400.4 hard drive is now shipping in volume to the worldwide distribution channel to meet demanding mainstream market requirements for capacity, performance and low power consumption.
