Seagate Momentus 7200.4 drives deliver the highest available laptop hard drive capacity while satisfying today?s need for desktop performance in a notebook computer. System builders can count on extending the life of their 7200-RPM laptops by eliminating the need to replace or upgrade due to performance obsolescence issues. All this without sacrificing battery life, because these new 7200-RPM drives draw only slightly more power than a 5400-RPM laptop drive.
