Each family's 18tb and 20tb high-capacity mechanical hard disks have come out one after another, but they are all enterprise products, which are very far away from ordinary consumers, and the price is also on the high side.
Seagate disclosed today that the 20tb hard disk for the mass consumer market will be launched in the second half of this year.
At present, it is only used for enterprise magnetic recording based on 20mr technology.
For 20tb hard disks in the consumer market, PMR vertical magnetic recording (enhanced TDMR plane magnetic recording) will be adopted in the initial stage, and 20tb SMR laminated magnetic recording is also being developed.
Seagate 14tb, 16TB and 18tb hard disks have used TDMR technology, the cost can be effectively controlled, and the cost of SMR is not high. They are very suitable for making relatively affordable 20tb hard disks.
In addition, Seagate is also developing related software to solve the problem of SMR write reliability, which can help optimize from more levels to ensure data security.
In terms of HAMR, Seagate will use it to manufacture 22tb and 24tb hard disks in the next step, but the time to market is to be determined.
