why does the fragmentation of large files occur into smaller files, arranged on different tracks? the read head then slows down when reading these scattered fragments in memory.

because the information is temporarily saved on the hard drive and therefore takes up space on the hard disk.
because it means that it is fully utilizing the ram but to avoid a crash it relies on the cache
