Seagate integrators and OEM customers are faced with an increasing demand for thinner yet fully functional mainstream laptop computing solutions. Until recently, the only option for these thinner solutions revolved around high-priced, slow performing 1.8-inch drives and high-priced, fast solid state drives.
