Issue Time:2017-12-18
Look at SSD in a threatening manner, mechanical hard disk did not slack, only constantly bulk products, while the price lower than do. It is said that Taobao has appeared on a new group of new / new HGST 8T enterprise plates, from the sluggish music of the cloud inside out, as long as a thousand yuan.

For now, the west, Toshiba released the 14TB, the former SMR (imbricate magnetic recording), which uses the traditional PMR (perpendicular magnetic recording), 9 disc helium filling.

Moreover, the giants have planned the 16TB hard disk, which is expected to be marketed next year.

Recently, Backblaze, a well-known storage service, reported that Seagate Mark (CTO) Mark Re introduced that HAMR (heat assisted magnetic recording) storage technology hard disk has been getting closer to commercial.

In October, the capacity density was 2Tbpsi (per square inch capacity). Mark Re revealed that it has reached 5Tbpsi now, which is 3.8 times the current Seagate's largest 12TB PMR (PMR) 1.3Tbpsi, and HAMR's final design goal is 10Tbpsi.

In addition, WD days ago announced a "MAMR microwave assisted magnetic recording" (microwave-assisted magnetic recording) and HAMR hard disk, difference is replaced with laser in HAMR as auxiliary media, using microwave shipments in 2019, known as the density of up to 4Tb.

Seagate once again emphasized the time node. In 2018, the trial production and display of 16TB HAMR hard disk and 2019 large scale production of 20TB over the mechanical hard drive, in 2023 increased the capacity to more than 40TB, 2030 launched 100TB.
