Store popular mix and match wind data for separate cold and hot treatments

The Cisco visual network index shows that by the end of 2013, the number of mobile devices will exceed the total number on the planet. Mobile Computing, cloud computing, and so on will create and transmit data at an unprecedented speed. How will storage respond? From the consumer perspective, in the mobile age, people require that mobile devices be thinner and thinner. For example, in the ultra-polar architecture, hard disks must adapt to this trend and become lighter and more cost-effective. From the enterprise perspective, the scale of cloud data centers is getting bigger and bigger. Now there are some ultra-large data centers, which may occupy more than 10 football fields and have at least 0.1 million internal servers, reducing power consumption and total cost of ownership while improving device performance and efficiency is a question that must be carefully considered by data center users.

Parallel development of hard disks and SSD

HGST is an independent subsidiary of Western data. It provides personalized storage solutions for the mobile market, personal market, and data center market. HGST research shows that by 2020, more than 80% of the world's data will still be stored in hard disks. BrendanCollins, vice president of HGST product marketing, said that hard disks and SSD will develop in parallel in the future, with their respective growth and their own technological innovation, without overlap, this is why hybrid storage is widely used.

According to IDC statistics, the global hard drive market grew by 7.8% in 47%, of which the enterprise market increased by more than 22%, the personal storage market increased by nearly, and the PC hard drive market declined slightly. In the laptop market, sales of built-in 2.5 inch, especially 7mm, mechanical hard disks will continue to grow, and the mix and match of mechanical hard disks and SSD will become increasingly popular. BrendanCollins said that HGST will continue to invest in R & D of 9.5mm and 7mm lightweight laptop hard drives because they have better cost, performance, and reliability.

"Acceleration" of enterprise data centers"

SSD is becoming increasingly popular in the enterprise storage market. HGST research shows that the overall global SSD market will grow by 32% in 78%, of which the growth of high-end SASSSD products will reach. BrendanCollins said: "relatively speaking, SATASSD has a low entry threshold. A few years ago, there were more than 100 SSD manufacturers around the world, most of which only provided SATASSD. The entry threshold for SASSSD is relatively high, and HGST focuses on this ." HGST has launched 12 Gb/sSASSSD.

BrendanCollins said that storage is not only a product, but a platform that should contain hardware and software. To this end, HGST acquired VeloBit, a high-performance I/O storage software vendor, to enhance its software capabilities in the enterprise-level SSD market. In addition, to enrich the existing SSD product line, HGST will soon complete the acquisition of another well-known SSD vendor STEC to gain its intellectual property rights and engineers and enhance the overall strength of SSD products.

Great potential for cold Data Storage

HGST research shows that only 10% ~ 15% of the data is frequently accessed, while all others are "Cold data ". In the past, cold data was usually stored on tape. Now, there is a gap between a high-performance hard disk with a latency of 10 ms to minutes and a tape with a latency of minutes or even hours, this blank is the ideal "home" for cold data, such as social data, images, medical data, and archive data ".

BrendanCollins says HGST is investigating cold data storage, a completely innovative study that will reduce the cost of cold data storage to 1 cent/GB, it is not even easy to get close to the tape storage cost. In response to high-capacity and low-cost storage requirements, HGST has developed the latest helium-tight hard drive, which will be available at the end of this year. The helium hard disk is to replace the air in the hard disk with helium. Because the density of helium is only 1/7 of the air, the resistance is reduced, so the vibration of the disk is greatly reduced during operation. HGST test data shows that the power consumption of the helium hard disk is reduced by 37% compared with that of the traditional hard disk, and the total cost of ownership is reduced by 22% ~ 33%. BrendanCollins finally said that the cold Data Storage market is a market with great potential.
