Seagate AcuTrac technology enables storage densities with accurate reading and writing to nano-sized tracks that are only 75 nanometers wide! That’s about 1/500th the size of the period at the end of this sentence.

The Size and Performance You Want

Your drive is up to 45% faster than the last generation thanks to Seagate OptiCache technology. OptiCache technology combines the latest advances in hard drive microprocessors, DRAM, and proprietary caching algorithms resulting in great performance improvements for you.

Go Beyond 2TB with DiscWizard Software

Free DiscWizard software from Seagate provides you a means to effectively utilize your 3TB and 4TB Seagate Desktop HDDs, even with Windows XP and using the standard PC BIOS.
