The compression ratio is very dependent on the uncompressed data (how compressible is the data?) and the compression algorithm.
There are generally two types of algorithms - lossless and lossy.
This is the command I'm using that works for extracting to non-existent locations: sudo unsquashfs -d /media/location1/locationthatdoesntexist /media/location2/file.squashfs I tried using this to extract to an empty partition,but it doesn't work: The difference between algorithms focuses on the techniques that create the new encoding. Duplicate files will be removed, so there will be only one physical instance (with SquashFS 2.x, you can disable the detection/rtemoval of the duplicates with the -no-duplicates option).

Since this article is about data it will focus on lossless algorithms that have an encoding that be reversed to recreate the data exactly. Distributions such as Debian Live, Mandriva One, Puppy Linux, Salix Live and Slax use this combination.
SquashFS, typically used for embedded systems, can be a great fit for laptops, desktops and, yes, even servers. http://squashfs.sourceforge.net/ regular file, directory, symbolic link, and block/char device inodes have different sizes). Let's say you have your floppy system tree at /home/user/floppylinux and you want to place the root file system on one floppy and /usr on another. In short, this means that you can freely modify and re-distribute the HOWTO under the main condition that you keep the author and copyright the article along.
