Earlier, the capacity unit of the hard disk was still on the GB level. At that time, the hard disk could hold several blue-light movies, thousands of photos and some songs. With the advancement of storage technology, the capacity of hard disk has begun to use TB (1TB = 1024 GB) as a unit, but the capacity of hard disk has not been improved too much, the mainstream mechanical hard disk capacity is 1TB and 2TB.

In recent years, a new storage device, solid-state hard disk, has been destroyed half way in the storage field. The solid-state hard disk completely abandons the disk components in the mechanical hard disk and uses chips to store data. Although the production cost of solid-state hard disk is higher than that of mechanical hard disk, the read and write performance of this kind of hard disk is several times better than that of mechanical hard disk. Suddenly, the status of mechanical hard disks has been reduced a lot. People have changed to solid-state hard disks to make system disks, and put mechanical hard disks into the cold corner, so that it can store some historical documents which may only be seen once or twice in a lifetime.

Indeed, the new storage technology has reduced the demand for large-capacity mechanical hard drives, but mechanical hard drives are still very useful. Because mechanical hard disks have an advantage over solid-state disks in capacity, many people will use mechanical hard disks as warehouse disks, and now the capacity of warehouse disks is moving towards higher capacity. Some time ago, Seagate, HGST and other mechanical hard disk manufacturers have created 10TB, 12TB or even more super-large capacity mechanical hard disks. These two kinds of hard disks are encapsulated with 8 disks, speed 7200rpm, SATA 6 Gps interface, 256MB cache, specifications are indeed much better than the previous small capacity mechanical hard disks.

In order to continue to increase the capacity of hard disks, every mechanical hard disk manufacturer wants to continue to heap hard disks, but the disk heap is too much and the hard disks are not stable. What can we do? So Seagate and HGST began to adopt a helium-filled technology, so that more disks could be packaged together. Among them, Seagate Cool Fish 12TB mechanical hard disk is packaged by helium technology. Eight disks are bundled together to get 12TB capacity. The same is true for HGST 12TB hard disk. Helium encapsulation technology is widely used in large capacity hard disk. The core of this technology is to use this inert gas to make the disk run more stable. In the sealed mechanical hard disk, Seagate and HGST use helium instead of the original air inside. Because the helium density is 1/7 of the air density, the pressure inside the mechanical hard disk is smaller than that outside. This can also improve the magnetic density inside the mechanical hard disk, ensure the stability of the internal disk and magnetic head, and ensure that the hard disk is more resistant to falling. In addition, helium-filled large-capacity mechanical hard drives can use thinner disks, so that the hard drives will not be too bulky.

It should be noted here that Seagate Cool Fish 12TB mechanical hard disk and HGST 12TB mechanical hard disk have adopted their own unique helium packaging technology, and have applied for patents. if you partition have been lost, you need some data recovery software forĀ lost partition recovery.

For consumers, 1TB, 2TB mechanical hard disks are enough now. If you install a 12TB mechanical hard disk in your computer, what will be the concept? That’s equivalent to multiplying your computer storage space, leaving you with countless photos, movies, and games of more than 60 GB in size. For enterprise users, a larger mechanical hard disk can bring about considerable improvements in data maintenance. Now the server’s requirement for storage hardware is constantly improving. The mechanical hard disk with large capacity and long life can just send charcoal in the snow and improve the storage performance of the server.

In terms of service life, according to Seagate official, Seagate Cool Fish 12TB hard disk supports 7 x 24-hour working requirements, with a maximum workload of 300 TB per year and 25 erases per year, while HGST 12TB mechanical hard disk has a maximum workload of 550 TB per year.

Seagate Cool Fish 12TB mechanical hard disk this time also added a new technology, called Multilayer Cache Technology (MTC), MTC can upgrade PC to a new level of performance, to load applications and files faster than before. By using NAND Flash Intelligent Layer, DRAM and Media Cache technology, Cool Fish Series hard drives can optimize data flow and provide better read and write performance.
