Kakaka is probably something that everyone who uses Android will encounter. It is very uncomfortable to open a picture and open an app. Due to Android’s default file system ext4, the more full the built-in flash memory is, the more the drawbacks of ext4 will be revealed. How to make the mobile phone run smoothly, the new F2Fs file management system is revealed:
Obviously it shows a great advantage in using the F2Fs file system in random read
What is F2FS?
F2FS is called Flash Friendly File System, which is a relatively new type of file system that supports Linux kernel. It was first developed and designed by Samsung in 2012, and its purpose is to better adapt to NAND and other flash memory devices (such as solid-state drives, eMMC and SD cards, etc.). In F2FS, Samsung has applied a log structure file system. The concept makes it more suitable for storage equipment.
In short, a new file system.
Where is the improvement of F2FS?
is mainly in the random read and write performance, and the random write performance is more obvious. Reflected in the actual use, it is the same storage medium and standard, the application opens a little faster cache pictures open faster.
F2FS affects life span?
Because of the difference in file system format, files with the same file size will be larger than those in EXT4, which will increase the amount of read and write to a certain extent. But it can be ignored, it basically does not exist, and there is no need to worry about meaninglessness.
The file in F2FS is larger than EXT4?
Yes, storing the same file in the F2FS file format will take up 1.1 times to 1.5 times the space compared to EXT4.
F2FS was born for running points?
The running score is only a means to reflect the objective situation, and everything is subject to actual experience.
F2FS's running scores, especially the results of the random read and write part, are really very good, which reflects the improvement in actual use, but it is far from the gap of several times that the running scores show.
Is F2FS running high? high.
Has the actual experience improved? Have.
Is there really such a big gap in running points? Obviously not.
Summary
F2FS is a technology whose advantages outweigh the disadvantages in a comprehensive view. The advantage is that the performance of random read and write is improved, and the disadvantage is that the performance loss under the condition of high storage occupancy and more storage space are occupied.
needs to be viewed rationally. This is a software technology, and it cannot be demanded to bring too many improvements. The improvement of its own hardware is far stronger than that of software.
But it does bring a nice improvement. As for how to define how good it is, it satisfies the ordinary people and makes the demanding people look down on it.
