ReiserFS has fast journaling, which means that you don''t spend your life waiting for fsck every time your laptop battery dies, or the UPS for your mission critical server gets its batteries disconnected accidentally by the UPS company''s service crew, or your kernel was not as ready for prime time as you hoped, or the silly thing decides you mounted it too many times today.
ReiserFS is based on fast balanced trees. Balanced trees are more robust in their performance, and are a more sophisticated algorithmic foundation for a filesystem. When we started our project, there was a consensus in the industry that balanced trees were too slow for filesystem usage patterns. We proved that if you just do them right they are better. We have fewer worst case performance scenarios than other filesystems and generally better overall performance. If you put 100,000 files in one directory, we think its fine; many other filesystems try to tell you that you are wrong to want to do it.
Linux: ReiserFS filesystem rocks!

I just re-formatted my linux partition with ReiserFS (comes with Slackware 9.0), and I''m impressed.
I''ll quote some description from the creators website, because their english is better than mine

I''ve never managed to get very excited about file systems. I didn''t notice much difference between using ReiserFS, ext2, and UFS. I only do programming and desktop style stuff though. My computer doesn''t crash that much either so the slow restart doesn''t bother me.
The ideas are interesting.

ReiserFS is uber. ext3''s journaling is pretty much crap, which is why a lot of distros are moving to Reiser as their fs for default installs (i believe mdk9.1 formats Reiser by default)
I''ve never tried Reiser, but I really like ext3. I''m going to switch to Gentoo in the summer (read: about 2 and a half weeks), so I might try Reiser when I use it.

I use reiser as my FS for my computer, very fast, reliable, and coupled with gentoo, makes me a very happy linux geek. I basically need a journalizing fs because law basically states, when I have a CS assignment due, my comptuer turns off some way or another. That killed me last term, I experimented with solaris 9, and a "friend" axed my computer''s power. Now I make sure journaling is present on any FS I have, and don''t let anyone near my computers.
If data hasn''t been written to your harddrive when your computer crashes or loses power ReiserFS doesn''t save it. I don''t know where you got that idea. That isn''t possible.

If it dies while you are saving, your old file is recovered and not half-written, scrambled, or generally gone forever (unlike DOS). And you can still boot since the OS files won''t get whacked either (unlike say, Win95).
If you''re impressed by file-systems, then you want to know about Netware, and their latest-and-greatest file system, NSS. Hardly the do-it-all OS Linux is, but you want a file server, Netware is hard to compete with.

no, I more was on the line, my machine lost power, my stuff was already saved, the inodes got corrupted, and fsck hosed my user dir.
