The Seagate Momentus

®

 XT drive offers hybrid storage 

with Adaptive Memory technology, enabling the drive 

to deliver higher capacities up to 500GB and SSD-like 

performance. 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 its performance to the user. Whether you are 

gaming, editing digital media or crunching numbers, the 

performance is optimized and ready for your next move.

Adaptive Memory technology is a Seagate data 

management technique that constantly monitors and 

quickly recalls data usage and preferences. It places 

fi les and data that the user will likely access again and 

again into the solid state portion of the drive. When the 

user requires the data or application fi le, it already sits 

in an instantly accessible location, thereby customizing 

system performance for the user. Constant monitoring 

dynamically improves overall response time based on 

personal usage. You can perform at your best no matter 

how you use your laptop PC.
