Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I'm considering use a different filesystem for the data drives of my NAS. These drives are for pure data (the root and home directories are elsewhere). For the most part, these drives are read from but not written to (my home movie and music collections, for example). The drives are almost full and for organizational reasons I'd prefer not to split them across two drives at the moment. I'm not running raid. The box runs 24/7, though I do spin the drives down when not in use. Windows compatibility is not an issue as I never take the drives out of the box. Also, most of the files are already compressed, so I'm not really considering filesystems that feature automatic compression.
At present I'm using ext4 for these filesystems but I read somewhere that ext4 is somewhat wasteful with the disk space. Also, since there's very little writing to disk I'm not sure I benefit from the journalling of ext4. On the other hand, if it's a very small amount of space used for journalling, perhaps it is still worth it.
Anyway, I'd like to not waste space on features I don't need. I'm having a hard time getting information about how efficient the various filesystems are in terms of space usage. Is there a ranking, or perhaps someone can point out their top few suggestions for my case?
