There are two options for this:

1) Mount the filesystem as ext2, and/or use tune2fs to eradicate the journal:

http://batleth.sapienti-sat.org/projects/FAQs/ext3-faq.html

2) Try setting the journaling mode to "writeback," which will only journal the filesystem metadata, not the actual data:

http://www.gentoo.org/doc/en/articles/l-afig-p8.xml#doc_chap4

From a data integrity standpoint, both of these are probably bad ideas. However, if your goal is to write data a little bit faster without much regard for whether or not it will be corrupted after a crash, it might be worth a shot.

I really, really wouldn't do this.

Ya, if you have to switch to ext2 to reduce disk IO you have bigger problems else where, find those, fix those. Journaling is a major part of any modern file system.
