transmission speed of 1.5GB per second, only 3 seconds to transmit a DVD disk data, 15 times the speed of the ordinary hard disk. It can be accessed 310 thousand times a second, while ordinary hard disk can only be accessed 16 times. These data describe the performance of a solid state disk. The world's fastest and best performing solid-state hard disk is developed by two "post-80s" - Yin Xuebing and his college classmate, Lu Xiangfeng.

[b] unintentional "Xintiandi" [/b]
in 2007, when Yin Xuebing worked at the CAS optoelectronic research institute, there was an aerial mapping project in the courtyard, requiring a large capacity hard disk to store data, but the traditional hard disk was too heavy and susceptible to vibration. The fault is now. No, they bought an imported solid state drive.
solid-state hard disk is the most sophisticated technology in storage field. Unlike traditional hard disk mechanical structure, solid hard disk is better than traditional hard disk, but the price is also very expensive - a solid state hard disk with capacity of 32GB is 5000 yuan, and a small 32GB U disk with a small size is only 100 yuan.
why is it so expensive? It surprised Yin Xuebing.
Yin Xuebing read a lot of data and found that there were very few producers of solid state drives in the world. Another embarrassing data shows that in the past ten years, the performance of CPU and memory has increased by more than 100 times, but the performance of hard disk has only increased two times. "The bottleneck of the entire data processing is on the hard disk." Yin Xuebing said that as long as we can get through this bottleneck, information transmission is on the "freeway".
think of here, Yin Xuebing's heart is not surging. This unintentional discovery brought the dream and reality that he had always had.
bottlenecks need to be opened up. Is this not the right way to make the "technology change the world" ideal?
photoelectric people want to go to SSD. It looks like a bit of a breeze. But Yin Xuebing was never a moment of fever. "I have been doing well in physics and chemistry. I started programming in high school. My undergraduate course is physics, and my master's degree is engineering." Yin Xuebing said that the solid state hard disk has integrated electronic information, computer, chip design, mathematics, physics and many other disciplines, belonging to the cross discipline, just to use his previous knowledge reserves.
[b] and instant noodles together for four years [/b]
said dry, Yin Xuebing found a good friend Lu Xiangfeng. During the day, they worked separately in the Chinese Academy of Sciences and Microsoft Asia Research Institute. After work, they gathered in the 9 square meter dormitory to start the experiment.
soon, Yin Xuebing found that their initial ideas were too optimistic, and the experiment failed to break through. "Solid state drives, storage media are used U disk mode, the core and difficulty lies in algorithm and architecture." Yin Xuebing, for example, requires an error correction function for information storage, so it is necessary to store some parity codes to restore and correct errors. In addition to the function of error correction, there are more than 10 core algorithms to prevent chip damage.
do it or not? Two people who dream of their dreams decide to continue, and decide to quit their highly paid jobs and concentrate on R & D. For the next two years, in Yin Xuebing's view, it was a "dark day" day - almost every day in the house to do some code and experiment, and a box of instant noodles in the house, their main rations. In 2011, after 4 years, they finally developed solid state hard disks. The results of the third party authoritative test software test show that the transmission speed, random access speed and response speed are more advanced than the world's largest solid state hard disk manufacturer in the United States, and the comprehensive performance is more than three times that of the competitors.
[b] 4 cm, 30 thousand yuan [/b]
, in Yin Xuebing, located in the HSI technology company, the reporter saw this solid-state hard disk product. The shape is almost as large as the traditional hard disk, but the surface of the solid state hard disk is not so smooth as the traditional hard disk, but is filled with a circuit board. It is embedded with 64 small blocks of black. This is a storage unit with a capacity of 16GB and a hard disk capacity of 1024GB.
in the inner wall of the circuit board, there is a chip of 4 cm square. Yin Xuebing said that the chip combines more than 10 sets of algorithms and architectures, is the brain of SSDs, and is also a reflection of the core technology of Heng Chuang source. Such a hard disk, although the price of up to 30 thousand yuan, can make the original to rely on five servers to complete the task, now can be done on a server.
with the accumulation of technology, financing and marketing are going smoothly. At the end of last year, recalling the band source infinity venture in Zhongguancun, a total of 20 million yuan of investment, the product has been renren.com, Qihoo 360, youku.com, LETV, Alipay, perfect world, the Chinese Academy of Sciences and other procurement.
next month, Yi Heng Chuang will move to an office space on the upper floor with an area of nearly 200 square meters, which is two times that of today. Yin Xuebing said that buying train tickets on the Internet, "double 11" Taobao rush to buy, and brush micro-blog all need high performance storage equipment, in the era of large data, the market value of solid state hard disk is self-evident.
