Seagate continues to bet heavily on large-capacity hard drives. These types of magnetic drives, although slower than SSDs, are still one of the cheapest options for increasing the capacity of a computer or data center.
Seagate Plans to Manufacture 50 TB and 100 TB HDD
Seagate estimates that, by 2026, they will be able to offer a capacity of up to 50TB, and of up to 100TB by 2030. Drives of up to 120TB are also among the possibilities for the beginning of the next decade.
Such large hard drives are going to require new magnetic recording technologies. As such, Seagate is working to perfect multi-actuator technology that promises to double the performance of hard drives, a technology that could become a standard for years to come.
Recently, Seagate began to produce hard drives of up to 20 TB in the conventional 3.5-inch format with magnetic recording technology (HAMR).
The manufacturer needs to increase the density of its magnetic platters in order to reach the 50 or 100 TB capacities. For example, to reach 40 TB, Seagate needs to increase the density to about 2,600 Gb / in2 (2.6 Tb / in2). To reach 105 TB, the capacity should be between 5,000 and 7,000 Gb / in2.
Seagate Dual Actuator Mach.2 technology is used in PMR-based experimental drives that are available to select customers. It is estimated that when hard drives typically reach 30TB, dual actuator technology will become a must-have feature to ensure good performance with large capacity drives.
Although costs will increase, Seagate is confident that hard drives will continue to be cheaper than SSDs.
