Hard drive manufacturer Seagate has laid out its near-term roadmap, with plans to increase drive capacities over the next few years. Seagate’s 10TB hard drives are now readily available, but the company has planned to reach production of 16TB magnetic drives in 2018 with 20TB drives to be available by 2020.
According to unit sales, SSD’s are taking over, with Seagate themselves revealing a 60TB Solid State to be released this year but the focus is still on magnetic drives according to the company.
In 2015, Western Digital revealed their 10TB hard disk drive (HDD) based on its HelioSeal Platform, which hermetically seals helium gas in the drive to decrease friction. At the time of publication, Western Digital’s HelioSeal 14TB is the highest capacity drive available to consumers. 4TB being the highest 2.5” drive (small external and laptop drives)
Western Digital, Seagate and Toshiba are currently the only manufacturers of drives. It is expected that we will reach 40TB by 2030 according to computer science analysts.
Innovation slowed in 2011 after the “Global Hard Disk Famine” caused by the 2011 Thailand Floods which drove up prices and dropped the availability of drives. Thailand is one of the world’s largest producers of HDD’s.
