A core technology that smart routing must break through-Hard Disk Protection

If 2013 was the first year of smart routing, 2014 would be the first year of its existence. In April 23, 2014, Xiaomi, who entered the routing field with Internet thinking, released two routers in Beijing Zhongguancun Software Park, a high-end vro with a built-in 1 TB hard drive, A vro with no built-in hard disks. Of course, the high-end version of the built-in 1 TB hard drive Xiaomi router naturally becomes the most eye-catching focus, because the general router is an external hard disk. So what is the difference between a built-in hard disk and an external hard disk?

Hard Disks are either built-in or external. In fact, many people have always misunderstood the concept of "built-in hard disk". The built-in storage hard disk mentioned here does not mean that the vro itself contains its own hard disk, instead, the vro contains a built-in hard disk warehouse where hard disks can be placed. A consistent hard disk can be placed in the hard disk warehouse to read files from the hard disk. There is no obvious difference in performance between the built-in hard disk and the external hard disk. The biggest difference between the built-in hard disk storage mode and the external hard disk is that the former places the hard disk inside the vro, the latter is connected to the router through the external USB port of the router. Generally, the built-in hard disk has high reliability and is more beautiful, while the external hard disk is easy to access, the USB interface is plug-and-play, and is conducive to the heat dissipation of the router. Therefore, the two hard disk storage methods have their own advantages.

Whether it is a built-in hard disk or an external hard disk, hard disk protection is still a problem that all vro manufacturers want to solve without exception. In theory, the theoretical life of a mechanical hard disk is more than 30 thousand hours, and the failure rate is doubled after six months of continuous start-up. Take the simplest storage medium-SD card as an example, in theory, the number of read and write operations on the SD card is about 0.1 million, and the embedded route works continuously for 24 hours. The risk of SD card damage is increased by 80% after read and write operations. Therefore, both the internal storage and external storage are started on the vro 24 hours a day, resulting in more serious loss of storage devices and extremely easy loss of user data. Therefore, professional hard disk protection is crucial.

At present, there are very few routing vendors on the market that have in-depth research in the hard disk protection field, including the recently popular Xiaomi route. From the perspective of Xiaomi's route design, Xiaomi will definitely start developing hard disk protection in the future. Because Xiaomi route writes all program systems in its built-in hard disk, during startup, because the built-in hard disk needs to run all programs, the router will generate a huge amount of heat, however, from the current release of the Xiaomi router, the Xiaomi router has not designed a dedicated routing hole to heat the huge heat produced by its router. The high temperature causes great damage to the hard disk. Once the built-in hard disk of the Xiaomi router is damaged due to the high temperature, the hard disk data will be lost, which leads to the crash of the entire system of the Xiaomi router. Therefore, solving the heat dissipation problem of Xiaomi routers and developing hard disk protection technology are two major problems that Xiaomi urgently needs to solve at this stage. According to insiders, the Xiaomi Team will consider using external fans to solve the problem of heat dissipation on its routers, and is also stepping up R & D of Hard Disk protection technology.

As the saying goes, there is a specialization in the industry. Xiaomi's core competitiveness is not a router after all. It still takes a long time to practice and evaluate the R & D of vro hard disk protection technology. As a matter of fact, in China, a routing manufacturer has already matured in hard disk protection technology, which is a leeching technology company from Chengdu. Chengdu longhear technology has been focusing on the development of cloud storage, and has been deeply developed by technology in the software. In August 2013, they launched the first private cloud smart router in China. With its high configuration, the cost-effectiveness of its products was quickly achieved in the routing industry.

Recently, the Lenovo cloud smart router jointly created by Chengdu lingting technology and Lenovo Group will be the first smart router in China to provide "professional hard disk protection, this smart router provides intelligent protection for hard disks by introducing high-end NAS hard disk protection technology. "Our sleep technology will be smart and automatic," said Li Cheng, CEO of NLP technology. For example, if a vro has no read/write requests within half an hour, the hard disk enters the semi-sleep state and the speed and power are reduced. If no read/write requests are received in the future, the vro automatically enters the deep sleep state, the hard disk stops running. Once there is a read/write request, the hard disk will be automatically awakened and ready ." At present, the Lenovo cloud smart router jointly created by Chengdu lingting technology and Lenovo Group has completed the public beta stage of the product in a low profile. This smart router is designed with an external hard disk, this avoids the high temperature of the built-in hard disk. In order to solve the problem of heat distribution of the router itself, the product R & D team of Yanqin technology and Lenovo Group has a wide hole design around and at the bottom of the router body. At the same time, Lenovo cloud router uses the professional NAS hard disk sleep Technology for the first time, sleep the hard disk in idle time, quickly recovers when busy, and enters the read/write status, avoiding the hard disk loss caused by frequent hard disk insertion and removal, the service life of the hard disk is greatly extended.

In fact, all the smart routers on the market can basically Mount hard disks. However, apart from Lenovo cloud's smart routers, which have professional hard disk protection technologies, other smart routers do not have mature and professional technical support in hard disk protection. As vro manufacturers continue to develop their own vro configurations and performance, people will pay more and more attention to hard disk data protection issues, the Lenovo vro jointly created by chengting listening technology and Lenovo Group is at the forefront of the times. I believe that the smart router market will not be lonely this summer.
