As the amount of data generated in various layers, such as individuals and businesses, increases worldwide every year, storage devices such as hard disk drives (HDD), solid state drives (SSD), and tape drives for data storage are also steadily increasing. Technological advancement continues. SSDs that are being pushed by SSDs, but are still going to be used for data storage for the time being, as well as SSDs that are showing very rapid technological progress, and tape technologies that are still in the limelight for archiving, are preparing for the future along with the current of each device. We looked at the status of technology development.
Estimated global data volume of 163ZB in 2025
The total amount of data generated worldwide is rapidly increasing year by year. According to a white paper published by HDD manufacturer Seagate Technology, which was commissioned by market research firm IDC, the data age 2025 was up to around 163 zettabytes (ZB) of data worldwide. It is expected to increase.
If you look at the terabyte (TB) unit that PC users are familiar with in order to take advantage of the sense of the unit called ZB, first, 1,024 TB is 1 petabyte (PB), and 1,024 PB is equivalent to 1 exabyte (EB). And only 1,024EB makes a unit of 1ZB. In other words, 1ZB is an enormous capacity equivalent to about 1.7337 million based on the 1TB HDD that is commonly used.
According to the 'Data Age 2025' white paper, the total amount of data worldwide by 2016 was about 16ZB. However, by the end of 2017, just a year later, the total amount of data is expected to increase to about 25ZB, and by 2025, less than 10 years ago, the total amount of data is expected to increase by about 10 times compared to 2016 to reach 163ZB. .
HDD launches 14TB product this year… Expected to achieve 40TB in 2025
As data explosion is expected, the continuous development of storage technology is also naturally required. First, if you look at the HDD, which is estimated to have been the most popular in the past, a product with a maximum capacity of 14TB based on a single HDD product has been released.
The storage capacity of 14TB is the first of its kind, an enterprise-class HDD 'Ultrastar Hs14', launched under the Western Digital HGST brand, while Western Digital, Seagate, Toshiba, etc. Is achieved. The 'Ultrastar Hs14' product applied 'SMR (Shingled Magnetic Recording)' technology that piles up the data track like a roof tile, achieving an increase in capacity and sequential write performance at the same time.
In particular, the new “Ultrastar Hs14” is based on the second-generation host-managed SMR technology optimized for sequential writing, as well as the fourth-generation helium charging drive technology “HelioSeal”. Products with “HelioSeal” technology that reduces air friction by sealing helium gas, overcome physical limitations of HDD and have advantages in terms of capacity, total cost of ownership, and density. As the capacity of a single HDD product increases, the same capacity can be realized with a smaller number of products, so it is possible to effectively lower the total cost of ownership (TCO) of the company based on the increased power efficiency.
On the other hand, it is also true that the realization of this increase in HDD capacity progressed more smoothly than originally expected. In 2015, the Western Consortium, Seagate and HGST formed a consortium of advanced storage technology consortiums (ASTCs) following the current PMR (vertical magnetic recording) technology, PMR +, and especially HAMR (Heat Assisted Magnetic Recording). And, based on HDMR + technology, it was expected that it would be possible to develop a HDD with a capacity of 100TB by 2025.
The PMR method, which is currently used in Western Digital and Seagate's 12TB HDD products, is a technique of vertically magnetizing data on the magnetic disk surface of a rotating platter and recording it.It appeared around 2006 and used the Longitudinal Recording. It has been replaced. However, HAMR technology, which was designated as the next-generation trend, faced material limitations and reliability problems, and the industry expects that it will be difficult to release a 100TB HDD by 2025.
Among these, it is noted that Western Digital recently announced that it is possible to launch a 40TB HDD based on a single product by 2025. It is based on the technology of "Micro ave-Assisted Magnetic Recording" (MAMR) developed by Carnegie Mellon University, a professor at Western Digital's Jimmy Zhu.
According to Western Digital, the core of MAMR technology is the 'spin torque oscillator', which is used to create a microwave field that improves data recording capabilities without loss of reliability even in ultra-high density environments. Is used. Based on this, Western Digital is using MAMR technology and expects to provide a recording density of 4 terabits per square inch (Tb, 4Tb is 500 GB) or more, and continuously improving the recording density to achieve a capacity of 40 TB or more by 2025. It is expected that development of a equipped HDD will be possible.
In terms of capacity, SSD overtaking HDD… Over 100TB
Currently, in the enterprise data center market, NAND flash memory, or SSD, is pushing the HDD with its speed and stability as a weapon and setting a new standard. In addition, although the price is high, SSDs also surpass HDDs in terms of capacity and show a very rapid technological development speed.
In particular, Samsung Electronics gained a technological advantage by mass-producing 15.36TB of Serial Attatched SCSI (SAS) SSD for the first time in the world since 2016 and supplying it to the enterprise storage market. Samsung Electronics also announced that it plans to release a 32TB SAS SSD within this year based on the fourth generation “V-NAND” technology with 512Gb (64GB) capacity.
