-- To create big dummy files really fast, use `truncate` (creates [sparse file](https://en.wikipedia.org/wiki/Sparse_file)) or
-  - `fallocate`: available for ext4, xfs, btrfs and ocfs2 filesystems
-  - `xfs_mkfile`: almost any filesystems, comes in xfsprogs package
-  - `mkfile`: is there for Unix-like systems like Solaris, Mac OS X etc
