While HDDs used in conventional notebooks are typically 9.5mm thick, HDD vendors have developed 7.5mm HDDs to suit slim ultrabook models, the sources indicated. As Intel requires reduced thicknesses for ultrabooks, WD has been making R&D efforts to reduce HDDs from 7.5mm to 5mm, the sources noted. Taiwan-based vendors Acer and Asustek Computer have adopted WD's 5mm HDDs and started design-in, the sources indicated.
5mm HDDs involve technological breakthroughs in components and manufacturing processes as well as modifications testing and specification certification, the sources pointed out. The cost of 5mm HDDs is expected to be higher than that of 7.5mm models and estimated to be 10% that of SDDs, the sources noted.
