Seagate's latest breakthrough ushers in the age of 55TB or even 69TB hard drives - and it isn't stopping there

• Seagate says it has achieved 6.9TB platters in its laboratory using HAMR technology
• Outgoing 30TB drives use ten 3TB platters for maximum storage
• Intermediate 4TB, 5TB, and 6TB platters will enter production in 2027–2029

Seagate has announced it has successfully developed 6.9TB platters in its laboratory, marking a significant milestone in future hard drive technology.

The company says these experimental platters more than double the capacity of those used in current commercial drives.

Outgoing models, such as Seagate’s 30TB HAMR hard drives, use ten 3TB platters to reach maximum capacity.
