What are the mainstream algorithms of all in one hdd docking station? from huangshenghong's blog

　　Solid state hard drives provide standard PCI and FC two interfaces for connecting to servers and hosts. DRM-based solid state drives mainly have two ways, respectively, SSD hard drives and SSD hard disk arrays. SSD's caching policy read and write performance is greatly improved, and the promotion of reading performance is more obvious. In addition, in the same number of SSDs, the SSD-based adaptive overhead sensitive caching strategy is significantly lower than the traditional caching strategy in the same system, which is effective to extend the service life of SSDs. What is the mainstream algorithm for all in one hdd docking station?

　　1. Advanced First Exchange Algorithm (FIFO Algorithm)

　　The essence of advanced first out algorithm is always selected to eliminate one page of long residence time (i.e., early). That is, first enter the home page, first exit the main memory. Its reason is to early-tune the page of the main memory, which is no longer used than the possibility of transferring the main memory. This algorithm is relatively simple, as long as the system retains a sequence table. The respective pages of the subsequence table record program enters the order of the main memory. Advanced first-out algorithms are easy to implement, and for programs accessed in linear order, the efficiency is not high for other situations. Because those that are often accessed, may stay in the main memory for a long time, and these commonly used pages have to be eliminated because of "old". It is estimated that when the advanced first out of this replacement algorithm, the shortage interruption rate is almost three times that of Excellent algorithm.

　　2. Eliminate algorithm (LRU algorithm)

　　The essence of the phase-out algorithm (LRU) is that when you need to replace one page, choose the page out of the last page that has not been used for a long time, the LRU algorithm is based on this theory, if a page is accessed, it is likely to be Access; the opposite, if it has not been used for a long time, it seems that it is not necessary to need it in the future. Realizing the true LRU algorithm is more troublesome, it must register the time experienced by each page, when needed to replace a page, select a longer page to eliminate the time.

　　All in One HDD Docking Station is not only the advanced algorithm, but also the accuracy and stability of the algorithm. It is generally necessary to deal with various difficulties, not only because of its own storage function, but more due to its environment adaptation Sexual and equipment adaptability, and with its growth in its research, it will increase in the future life and functionality, so it will be more convenient in reality.
