500GB Seagate Momentus SATA 2.5-inch laptop hard drive (7200rpm, 16MB cache) ST9500423AS by Seagate

Seagate Momentus 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.

When it comes to getting more time back in your day, nothing feels better than a well-performing laptop. Seagate's Momentus 7200-RPM drives can give precious moments back when you really need them. In fact, Seagate 7200-RPM drives can shut your system down 34 percent faster, and opening big files can be up to 30 seconds faster than a 5400-RPM drive can manage. When it’s your turn to shine, your 7200-RPM Seagate drive won’t keep you waiting.
