Re: [tlug] SSD filesystem

Seems everyone has an opinion on which filesystem and settings are best for an SSD drive. Some say journaling filesystems like ext3 will wear out the drive sooner though opponents argue that failure from overwriting is exaggerated. Others recommend ext4 to get even better performance out of a high speed SSD.

I'm currently using the following at the recommendation of a blog post from a person who seemed to know what he was talking about.

/ ext4 noatime,barrier=0,data=writeback,nobh,commit=100,nouser_xattr 0 1
/home ext4 noatime,barrier=0,data=writeback,nobh,commit=100,nouser_xattr 0 1

This is on a Latitude E4200 with the ultra 64 SSD running Ubuntu Jaunty in case that matters.

Any feedback is appreciated.

Hello Kyle,

Please check out NILFS (developed by NTT) : http://www.berkeleylug.com/?p=202

I came across this interesting article this morning. It is released under the GPL 2.0 license and is included in the 2.6.30 kernel.
