With the increase in demand in the digital field of science and technology, people’s demand for hard disk storage capacity is also increasing, and 20TB HDD has gradually begun to be used for civilian use around the world. Seagate is the first company in the world to launch a 20TB HDD, and Seagate also launched two new 20TB HDDs a few days ago.
Regarding HAMR (heat-assisted magnetic recording), the CEO said that Western Digital has invested a lot of money and manpower in it, and the technology will gradually mature in the future and officially debut. It also stated that HAMR is the key to further increasing the capacity of HDD. There are currently more than 400 patents on HAMR, but it also requires a lot of software design to support it, so it is still a few years away from commercialization.
Not only that, Western Digital even set a more ambitious goal-30TB HDD, CEO David Goeckeler said that Western Digital currently has SMR, OptiNAND, ePMR, and other technologies, which are the basic techniques to achieve the 30TB capacity goal.
