Seagate ships bigger, faster, safer 2.5" drive

A week ago, Fujitsu announced what it claimed to be the world's first 7200RPM 2.5" notebook hard drive with support for 300MB/s Serial ATA transfer speeds. Seagate has responded by actually shipping a line of 2.5" notebook hard drives that combine 7200RPM spindle speeds, 300MB/s Serial ATA transfer speeds, capacities of up to 160GB (thanks to perpendicular recording technology), and a little something to make them stand out: free-fall protection. The new Momentus 7200.2 hard drives are built to support up to 900Gs of non-operating shock and 350Gs of operating shock, and they come with an optional free-fall sensor that can detect changes in acceleration equal to the force of gravity and park a drive's head off the disk to minimize the chance of a head crash. The mechanism, Seagate says, works quickly enough to withstand falls of as little as eight inches (20cm).
