Most people that i know of that are professionals either in the video editing business or in graphics designing own several Terabytes of data while some of them working for some of the leading movie studios have as much as 120TBs of total storage. I am certainly not excluding ourselves since currently for backup purposes along we using exactly 28TBs and that's without including the 22TBs which we have attached on all 3 of our test rigs for daily use. Unfortunately although storage capacity needs get higher each day that goes by we still haven't seen any 5TB hard disk drive models get unveiled from all the leading manufacturers and although both HGST and Seagate have announced technologies that should allow the manufacture of mechanical drives up to 20TB in capacity (if not more since technology advances all the time) by the end of this decade that's really of little concern right now. Still sales of 4TB drives have been increasing steadily around the globe and since some of you asked today we will be taking a look at the latest Touro Desk Pro 4TB USB 3.0 External HDD by HGST.
