Momentus 7200.4 SATA 3Gb/s 500-GB Hard Drive
ST9500420ASG

The Seagate Momentus 7200.4 drive delivers the highest available capacity on a laptop hard drive while satisfying todays need for performance. System builders can count on extending the life of their 7200-RPM laptops by eliminating the need to replace or upgrade due to performance issues. All this without sacrificing battery life, because these new 7200-RPM drives draw only slightly more power than a 5400-RPM laptop drive. For hardcore road warriors or aspiring warriors in need of extra robustness, G-Force Protection technology provides enhanced data protection against shock that may occur while the drive is operating.
