Eine recht kurze, aber IMHO trotzdem ganz nette Beschreibung der verschiedenen Filesysteme findet man im Gentoo Linux Install Guide:

Now, on to filesystem types. Right now, you have four filesystem options: XFS, ext2, ext3 (journaling) and ReiserFS. ext2 is the tried and true Linux filesystem but doesn't have metadata journaling. ext3 is the new version of ext2 with both metadata journaling and ordered data writes, effectively providing data journaling as well. ReiserFS is a B*-tree based filesystem that has very good small file performance, and greatly outperforms both ext2 and ext3 when dealing with small files (files less than 4k), often by a factor of 10x-15x. ReiserFS also scales extremely well and has metadata journaling. As of kernel 2.4.18+, ReiserFS is finally rock-solid and highly recommended. XFS is an filesystem with metadata journaling that is fully supported under Gentoo Linux's xfs-sources kernel.

If you're looking for the most standard filesystem, use ext2. If you're looking for the most rugged journalled filesystem, use ext3. If you're looking for a high-performance filesystem with journaling support, use ReiserFS; both ext3 and ReiserFS are mature and refined. Please be careful with XFS; this filesystem has a tendency to fry lots of data if the system crashes or you lose power. Originally, it seemed like a promising filesystem but it now appears that this tendency to lose data is a major achilles' heel.

Wenn ich demnächst Gentoo 1.4 auf meinem Notebook installiere werde ich wohl auf allen Partitionen außer /boot (die bleibt ext3) ReiserFS einsetzen.
