- Seagate says it has achieved 6.9TB platters in its laboratory utilizing HAMR expertise
- Outgoing 30TB drives use ten 3TB platters for optimum storage
- Intermediate 4TB, 5TB, and 6TB platters will enter manufacturing in 2027–2029
Seagate has introduced it has efficiently developed 6.9TB platters in its laboratory, marking a big milestone in future onerous drive expertise.
The corporate says these experimental platters greater than double the capability of these utilized in present industrial drives.
Outgoing fashions, corresponding to Seagate’s 30TB HAMR onerous drives, use ten 3TB platters to achieve most capability.
HAMR expertise and storage density
With the brand new 6.9TB platters, a single onerous drive may obtain between 55TB and 69TB whereas sustaining the identical bodily type issue.
This stage of storage density has not but been carried out in shopper or enterprise merchandise, nevertheless it demonstrates the bodily limits of contemporary HAMR expertise.
The high-capacity platters depend on Seagate’s heat-assisted magnetic recording, or HAMR, which applies warmth to cut back magnetic coercivity in the course of the write course of.
This enables information to be saved extra densely than on standard onerous drives.
In present drives, HAMR is mixed with strategies corresponding to Mozaic 3+ to cut back the media grain measurement and enhance recording precision.
By making use of these advances to bigger platters, Seagate has created the potential for drives that would retailer greater than twice the information of present fashions with out rising measurement or weight.
Seagate has indicated that 6.9TB platters won’t be utilized in official merchandise till round 2030.
Earlier than then, the corporate is creating intermediate platters of 4TB, 5TB, and 6TB, with manufacturing anticipated in 2027, 2028, and 2029, respectively.
Past 2031, Seagate initiatives even bigger platters starting from 7TB to 15TB, suggesting the potential of petabyte-sized onerous drives earlier than 2040.
Regardless of the rise of SSDs, onerous drives stay essential for large-scale storage as a consequence of their superior capability per greenback and long-term reliability.
The AI increase has intensified demand, leading to prolonged backorders for enterprise-class drives.
Whereas consumer-focused storage options like USB drives and smaller SSDs are gaining reputation, high-capacity onerous drives stay a spine for information facilities and archival storage.
