TDK roadmap suggests 2.5TB HDDs are just around the corner
 

Hard drive head manufacturer TDK has recently made available a little chart that provides new info regarding the hard drive capacity updates coming throughout this year. In the 3.5-inch zone, the next step up is a 640GB platter, which is expected to start being used as of next month and adopted by all major HDD manufacturers by November.

The move from 500GB to 640GB will enable companies to make and sell 3.5-inch drives with a 2.5TB capacity (using 4 platters) or even 3TB (5 platters).
