Samsung yesterday introduced a new 2.5-inch portable hard drive model, the Spinpoint MP4 with 640GB capacity and 7,200RPM. Its performance promises to be up to 30% higher than the 5,400RPM versions, even more because its internal cache has been doubled to 16MB.
To enable the production of the new HD models, Samsung has implemented a dynamic balancing technology that solves reliability problems caused by the high vibration of previous 7200RPM models. Now, they have managed to create a very quiet model during their operation.
With a 3Gbps SATA interface, the Spinpoint MP4 should be available for OEMs this month, with models starting at 250GB. Samsung has not released official prices yet, however.
