Abstract

As a particular data file stored on disk grows in size, additional sections of disk storage space must be allocated to that file. If the storage sections are kept small, the loss of disk file space due to internal fragmentation (unused space on the last assigned file segment) is kept small. However, for large files, the speed and efficiency of accessing the data on the disk is substantially reduced because the large number of small disk storage sections allocated to that large file will be dispersed over the disk, and must be separately accessed by the disk operating system.
