Laptop computer storage is <A HREF="http://www.cio.com/article/187997/Fujitsu_Latest_to_Show_GB_Laptop_Drive">racing fast towards the 500GB level</A> with Fujitsu becoming the third hard-disk drive maker to announce a drive at that capacity.
Fujitsu is accomplishing this capacity by combining three disk platters--the magnetically-coated disks on which data is stored--each with a 170GB capacity inside the drive. Hitachi, the first company to announce a 500GB drive, and Samsung Electronics are also using three platter designs.
