As devices get thinner and thinner, there's no place in that world for chunky hard drives, and to that end Western Digital has been talking about bringing ultra-thin 5mm hybrid drive technology to the market. The new technology will be branded WD Black, and consist of a 500GB, 5mm thick (or thin) model with 24GB of NAND memory, along with a 1GB, 7mm model that also has 24GB of NAND. WD has already started shipping copies of the new models to OEMs, and expects that they'll land in the hands of consumers within the next 6 months. We'll have a hands-on video coming up shortly.
