analysis of disk layout of F2FS file system F2FS divides the entire volume into segments, with a fixed size of 2 MB per Segment. Several successive segments constitute the section, and several successive Sections constitute the Zone. By default, a Zone large size is a section, and a section size is a Segment. F2FS divides the entire volume into 6 areas, except for the
