Hybrid 2.5 inch ssd-hard drive released

Seagate release a 2.5 inch hybrid hard drive/SSD. Click the thumbnail below for the specs.

The Seagate Momentus XT will initially be available in three capacities—250GB, 320GB, and 500GB. The drives conform to the 2.5” form factor with 9.5mm Z-Height, and they sport standard SATA 3.0Gb/s interfaces. 32MB of DRAM cache is also incorporated into the drives. Spindle speed is 7200RPM.

How fast is it?

Performance Summary: The Seagate Momentus XT produced some interesting performance results. In the purely synthetic tests designed to test raw throughput, the Momentus XT generally performed like a high-end, 7200 RPM hard drive--transfer rates typically fell between the WD Scorpio Blue and Seagate Barracuda desktop drive. In the system level benchmarks like those employed in PCMark Vantage, however, once the Momentus XT's adaptive memory technology learned the usage patterns and copied over the most commonly accessed bits of data to the solid state portion of the drive, performance improved dramatically. The Momentus XT was never able to truly match the performance of a true SSD, but its performance when the adaptive memory technology was used was far superior than a standard HD.
