Seagate to release 25TB and 30TB hard drives this year
Last year, a Seagate Osprey (STL022) hard drive appeared on the list of SATA-IO integrators, which means that the hard drive has passed the SATA interoperability test. Its part number is STxxxxxNM0092-3CX103, which means it is very likely to have a capacity of 22TB.
According to TomsHardware, Seagate plans to significantly increase the capacity of hard drives this year, launching new 22TB and 24TB hard drives in the first or second quarter. In the third quarter, the industry’s first hard drive using the second-generation HAMR (heat-assisted magnetic recording) technology will be released, providing a capacity of more than 30TB.
Seagate CEO Dave Mosley said hard drives with a capacity of 30 terabytes or more could launch in June, slightly earlier than initially planned. The speed of its mass production depends on many factors, including production capacity and the timetable of customer qualification certification. Seagate will also use its system to speed up the progress. Hard disks with a capacity of 20TB or above are based on traditional PMR, and some customers can choose SMR as an additional function to slightly increase capacity.
It is understood that the new generation of HAMR technology has different requirements for hard disk media, magnetic disks, magnetic heads, controllers, and cache mechanisms. Some people in the industry speculate that it will be more difficult and costly to manufacture new parts. At 30TB and above with a single drive, performance degrades with capacity, so Seagate has expanded its Mach.2 technology with dual drives.
