Large data Age: five technology or will change storage development

The field of data storage is undergoing drastic changes, and this change will be a long-term trend. And with the change in the data storage field, will inevitably give birth to some of the new technology, will change the development of the storage area, so today we will look at what storage technology in the future will change the future?

1 Ethernet Hard Drive

Seagate has announced its Ethernet-connected Kinetic drive, which claims that Ethernet hard drives will provide four times times more storage-application performance than is currently possible.

The design idea of Ethernet hard disk is very obvious, is to streamline the transmission between the data to the hard disk (that is, the data does not need to be from the server to the HBA card and the array controller is finally written to the hard disk, in the Ethernet hard disk system, the data can be directly through the network to the hard disk of the Ethernet interface and then stored in the

The advantages of Ethernet drives are obvious, but they also face a lot of challenges, with Seagate and HGST currently being introduced into the Ethernet drive,

2 Helium filled disk

HGST before the launch of its first 6TB helium-filled hard drive filled with helium, the advantage of this product is that it can use more rotary disk drives to increase product performance. and helium provides smaller resistance to prevent platters because excessive friction causes more heat consumption.

3 High Performance phase change memory/NAND hybrid solid-state storage.

Phase change memory (PCM) is a standard NAND (Flash) memory used as an alternative to solid-state hard disk (SSD). Phase change memory (PCM) is a non-volatile storage device that uses reversible phase transformation of materials to store information. Is the use of special materials in different phases of the resistance difference between the work.

IBM expects that on this basis the hybrid PCM technology storage product will be in 2016 years.

4 IBM 154TB Tapes

In May 2014, IBM and Fuji Film have released a demonstration of a 154TB LTO tape library, and will be officially launched in the next 10 years. Although this level is lower than Sony's 185TB, but with its own strong tape partnership network, IBM has a full opportunity to drive Sony out of the arena.

The Advanced servo control technology enables the magnetic head to be accurately positioned at the nanometer level, allowing the orbital density of the new scheme to reach 28 times times the existing LTO6 format. The new signal processing algorithm makes the running state more reliable and is equipped with a very precise reading mechanism of the 90 nanometer magnetic giant Head (GMR).

5) Genetic Storage

Harvard researchers coded a book of about 53,400 words into less than one Sark (one out of 10,000 grams) of DNA microchips and then successfully used DNA sequencing to read the book. This is by far the largest experiment in the use of DNA genetic material by humans to store data.

DNA molecules are also very dense storage media, so 1 grams of DNA can be 2000TB to keep the data.
