Seagate plans to introduce 120TB capacity hard disk drives (HDDs) in 2030.
Seagate plans to launch a 100TB hard drive in less than 10 years, 5 times the capacity of today’s largest hard disk drives (HDDs). In fact, Seagate wants to increase its single-drive storage capabilities to 120TB and beyond some time after 2030. The company plans to launch 30 TB+ hdds in 2023, then 40 TB+ in 2025 and 50 TB hdds in 2026.
The company’s recently updated storage roadmap reminds us once again that HDDs are not dead. It was even shared that HDDs created more than one zettabyte (1,000,000,000,000,000,000,000,000 bytes) of shipped storage last year.
Heat-assisted magnetic recording (HAMR) technology plays an important role in Seagate’s effort to greatly increase storage capacities. HAMR is a technology designed to provide the next big increase in the amount of data that can be stored on a hard drive. This method allows data bits or particles to become smaller on each disk and pack more intensively than ever before while remaining magnetically stable. Each recording heats a small point on the diode disc, which allows the recording head to translate the magnetic polarity of each very stable bit, paving the way for the data to be written.
Seagate talks about the need to move beyond vertical magnetic recording (PMR) to continue to increase capacities. As pmr technology approaches its maximum useful capacity, each successive disk increases by 1 TB or 2 TB at a time, while HAMR technology provides 4 TB, 6 TB and even 10 TB steps at a time. The company also talked about adopting completely bit-patterned media (BPM) to reach increasing capacities. In this way, it is emphasized that the maximum area density will be increased from 2.6 terib per square inch to more than 8 Tb per square inch.
Let’s also remember that Seagate launched 20 TB HAMR HDD models at the end of January.
