Hard drives just keep getting more and more capacity. At CES, Samsung has unveiled the new Spinpoint M6, the world’s first 2.5 inch hard drive with a 500GB capacity. It’s actually made up of three separate 166GB platters, but the three fit together to be just 9.5 mm tall, so it can fit into any number of different devices without causing a particular size challenge. Simple physics and math will tell you that you could get a terabyte of storage capacity by putting two drives in a notebook. The Spinpoint M6 has a 5400 rpm spindle speed, an 8MB and a 3.0Gbps SATA interface. Samsung also included their Flyiing on Demand head technology which provides for improved recording stability when the temperature is changing. A free fall sensor and a rotational vibration sensor are available as optional features. The drive is expected to hit the market at March, at an as yet unknown price.
