Solid-state memory technology is the main competitor of magnetic recording disk drives on the market, but the expansion of the first constrain the high cost and controversial trend to change the parameters of reliability as we move to more advanced lithography processes.
Western Digital does not believe that the proliferation of solid-state drives has significantly changed the market in recent times. Yes, the volume of disk platters sales are reduced, but not because the SSD hard drives. Solid state drives come with the mobile market - they are used in tablets, and other thin mobile devices . Partially WD gather here to strengthen its position through the supply of thin hybrid drives. They have sufficient volume and speed, and thus are much less similar SSDs capacity .
WD estimated , even to the end of the decade up to 85% of all data will be stored on storage devices with rotating magnetic plates. Of course, some of these drives will move from personal computers and servers in the "cloud", but the essence remains the same .
