One thing to stay up for: Producers have spent years attempting to push spinning disk drives over the 30TB mark, and the purpose seems to be imminently inside attain. Seagate’s funding in rising HDD know-how has struggled to achieve acceptable yields, however the firm stays decided to press onward.
Seagate’s latest fiscal assertion confirms their dedication to provoke the manufacturing of 30TB arduous drives in early 2024. Though reaching this capability has been a longstanding problem, the corporate is intent on accelerating its efforts all through the last decade.
The corporate’s newest quarterly report outlines plans to spice up the quantity manufacturing of HDDs with a 3TB per platter capability early subsequent 12 months. Seagate’s largest drives that cater to enterprise shoppers incorporate 10 platters, making up for a 30TB capability. HDDs with fewer platters could quickly be supplied to consumer-level customers.
Trade tendencies recommend that standard magnetic recording strategies have plateaued at round two and a half terabytes per platter. Seagate plans to produce 24TB and 28TB drives utilizing the mature know-how by the top of the 12 months earlier than totally transitioning to HAMR (Warmth-Assisted Magnetic Recording), which it sees as the longer term, in 2024.
HAMR know-how employs lasers to transiently warmth particular disc segments, enhancing information density whereas preserving thermal stability. Seagate has confronted hurdles in reaching acceptable yields with HAMR for a while however has managed to provide a restricted batch of 32TB drives utilizing second-generation HAMR for launch in late 2023.
Ought to Seagate handle to scale up manufacturing on the onset of subsequent 12 months, the following milestone could be 4TB per platter, probably resulting in 40TB HDDs throughout the following two years, as projected of their stories. Drives with a 50TB capability, holding 5TB per platter, are anticipated by 2026, with preliminary roadmaps aiming for 100TB by 2030.
Seagate just isn’t the only contender within the HAMR house. Western Digital initially guess on microwave-assisted magnetic recording however shifted to HAMR after a number of years. Earlier within the 12 months, the corporate indicated it was about one to 1 and a half years from quantity manufacturing with HAMR.
Like Seagate, WD acknowledges that standard recording know-how is reaching the top of the highway within the 20s. The corporate, too, aspires to finally attain 50TB and presumably past.
Stable-state drives of comparable capacities, such because the 61.44TB Solidigm P5336 geared towards enterprise use, exist already. Nonetheless, some shoppers could proceed to favor HDDs for his or her significantly decrease value.
