2.5 TB HDD Expected in 2010
 

By January 2010 we should be seeing 620GB 2.5-inch and 2.5TB 3.5-inch hard disk drives, according to head manufacturer TDK Corporation.

A presentation to financial analysts, including Stifel Nicolaus' Aaron Rakers, contained a roadmap for hard disk drive (HDD) read/write heads which TDK manufactures for some HDD suppliers. The current highest density read/write heads it is mass producing are for 250GB/platter 2.5-inch or small form factor (SFF) drives and for 500GB/platter 3.5-inch disk drives.
