Intelligent Transportation
In recent years, China's high-speed rail has developed rapidly and is now at the top level in the world. At the same time, the rail transit industry is also an important category of industry. In the field of rail transit, there are several scenarios where industrial-grade SSDs will be used, such as gates, PIS, roadside equipment, and on-board intelligent equipment (such as 3C monitoring, rail monitoring), etc.
Request
Vehicle-mounted intelligent equipment is one of the most demanding scenarios, because the use of such application scenarios is harsh because the requirements for SSDs are in terms of temperature, humidity, vibration, dust, mold, abnormal power failure, and vibration. There are strict requirements in all aspects. In addition to the above external environmental requirements, there are also the following requirements for SSD writing, such as heavy load writing pressure, and Flash particle life requirements. Because consumer-grade SSDs cannot meet the requirements of high-speed rail and subways, consumer-grade SSDs are not as demanding as industrial-grade SSDs in performance testing of their own hard drives.
Solution
The rail transit industry has its own characteristics: SSDs account for less than 5% of equipment costs, but will bring more than 50% of after-sales workload; communication is a key component, and the operating system is deployed on SSDs or data is stored in SSDs. A failure occurred, causing the entire machine to go down. The failure rate of ordinary SSD is about 3%. Considering the huge installed capacity, the overall after-sales maintenance workload is very high; ordinary SSD have a one-year warranty and a short lifespan. After 1-2 years of use of ordinary solid-state hard drives, due to device aging and life consumption, the failure rate increases sharply. Due to the above series of characteristics and requirements, it is necessary to require the hard disk to use industrial-grade SSD. As a R&D and production service provider focusing on high-reliability industrial-grade SSD and memory cards for many years, Agrade serves every customer with its own professional attitude and strict attitude. Unanimous praise from customers.
Agrade Advantage
Because of years of persistence and innovation, many well-known rail transit companies have introduced Agrade industrial-grade SSD. Because after using Agrade industrial-grade SSD, they found that Agrade industrial-grade SSD can reduce the AFR failure rate to the 10,000th place. Compared with the products they used before, the failure rate has been greatly reduced, saving a lot of maintenance pressure. And because of Agrade’s strict testing and product quality control, in order to ensure the high reliability and high stability of its products, the failure rate of its own products has been very low, and the benefits are very prominent.
