5 TB 3.5 inch hard drives maybe coming soon…in the next 2 years or so.
Hitachi has pledged to release a 5TB 3.5in hard drive within two years, and it claims two of the drives will boast enough capacity to store everything in your brain.
According to a report by Nikkei Net, Hitachi Global Storage Technologies will use Current-Perpendicular-to-Plane Giant Magnetoresistance (CPP-GMR) magnetc read heads to achieve the aim. This, the firm claims, will allow its drives to store 1TB of data in every square inch of the recording surface.
