Few people know that Hitachi was the first manufacturer to break the 1 TB hard disk barrier. Well, they are a force in this field of activity and they come now with something else that is definitely amazing. Hitachi steps up with a claim that they will release a 4TB 3.5 inch hard disk drive and a 1TB laptop 2.5 inch hard disk drive in the next 4 years. It looks like the new recording heads will be around 2,000 times smaller than human hair. Ain’t that something? It will be interesting to see whether or not this will appear sooner and it will definitely bring in a need for other manufacturers to improve personal computer and laptop specs in the near future. Technology is evolving at an incredible rate. Soon my personal laptop will be out of date, although I just purchased it!
