Momentus® XT

Powerful, Intelligent, Affordable—Solid State Hybrid Drive

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.
