The Momentus XT drive is designed for all standard laptop PCs and is OS-, driver- and software-independent, making this drive easy to integrate and easy to use. Adaptive Memory technology enables the drive to tailor performance to the user. Whether you are gaming, editing digital media or crunching numbers, performance is optimized and ready for your next move.
Hybrid Hard Drive
Designed with high-performance core components on an innovative platform, the Seagate Momentus XT solid state hybrid drive consists of a 7200-RPM hard drive with 32MB of cache, 4GB of solid state SLC NAND flash storage, and Adaptive Memory technology, delivering an 80 percent faster performance than traditional 7200RPM hard drives.
The average read speed on those drives is 82MB/s to 85 MB/s. Not really much different than the standard Momentus 7200 drives actually. I was not impressed.
