the metadata information. Obviously, the larger the file system to be detected, the longer the detection process takes. For partitions with a size of dozens of G, it can take a long time to detect. As Linux starts to be used for more and more important applications in large servers, it is becoming more and more intolerable for long time machines. This requires more sophisticated and sophisticated file systems

that the disk's seek time doubles and disk performance degrades. For scenario two, if the disk C, only the head in the 1-1000 tracks between the movement can be, greatly reducing the seek time. (In fact, the partition does not start at 0, and the first track of the disk will be used to install the boot loader and the disk partition table). Therefore, the partitioning method of scenario two can reduce the disk IO time in the seek time part, so all operating
