I just learned how to turn filesystem journaling on and off using the diskutil command. I'm thinking I probably don't need it on. I mean, journaling is mostly useful if you have mission-critical files that are frequently being modified, like on a web server or banking system. I don't think it's really that beneficial for a laptop that I just use as my personal computer. On the other hand, turning filesystem journaling off might result in a slight performance boost since there would be less disk thrashing (I'm using an older Macbook with a magnetic hard drive, not one of the newer SSDs). What do you think?
I googled based on your title and the first hit answers your question.

If your laptop every runs out of power, it sounds to me that you will want journaling on.
But suit yourself, just know the risks.
