fallocate is used to preallocate blocks to a file. For filesystems that support the “fallocate” system call, this is done quickly by allocating blocks and marking them as uninitialised, thus requiring no I/O to the data blocks. This is a much faster method of creating a file rather than filling it with zeros.
