Intended usage is over raw flash devices on embedded systems like ARM and MIPS, the filesystem is less suitable for use on consumer SSD[2] (because consumer SSDs already make sure to not use the same physical blocks for writing modified data). StructureSimilar to UBIFS, the CHFS file system utilizes a separate layer for handling Flash aging and bad blocks, called EBH (erase block handler). The file system itself is modelled after JFFS2, thus the internal structure is very similar. ChewieFSCHFS was originally called ChewieFS during development.[1] The name was changed to avoid legal issues{{fact|date=March 2019}} and to have a more neutral name.{{fact|date=March 2019}} See also
