Seagate Officially Launches Hybrid Hard Drive

We knew Seagate was cooking up a hybrid hard drive that would combine an SSD and HDD under the same hood, but most of the information we had was based on speculation and leaked specs. Things are a bit more concrete now, as Seagate today officially unveiled what it claims is the "world's fastest hard drive for laptop computers."

It's called the Momentus XT and it comes in three capacities, including 250GB, 320GB, and 500GB. These hybrid drives will sport 4GB of fast SLC NAND solid state memory, a 7200RPM spindle speed, 32MB of drive-level cache, and SATA 3Gb/s with NCQ.

"We see the Momentus ® XT drive as a game changer, a product heralding a new generation of hard drives that combine SSD and HDD capabilities so that laptop users don’t have to make trade-offs on speed, cost or capacity," said Dave Mosley, Seagate executive vice president of Sales, Marketing and Product Line Management.

To squeeze the most performance out of its hybrid drive, Seagate has implemented what it calls Adaptive Memory technology. What this does is analyze patterns in how often certain digital data is used and then moves the most frequently used bits to the embedded solid state memory for faster access.
