Ubuntu 12.04 LTS - Benchmarking All The Linux File-Systems
Phoronix: Ubuntu 12.04 LTS - Benchmarking All The Linux File-Systems
When running Linux file-system benchmarks at Phoronix it is most often a comparison of EXT4 vs. Btrfs, since they are the "hot" Linux file-systems at the moment. Sometimes others like ZFS, Reiser4, and XFS also join the party. In this article is a look at all of the Linux file-systems with install-time support under the forthcoming Ubuntu 12.04 LTS. When carrying out clean installations each time with changing out the root file-system and using the default mount options, ReiserFS, JFS, EXT2, EXT3, EXT4, Btrfs, and XFS are all being compared in this article.
the FS that do not support fsync on some benches should be removed from the final chart as they do nothing except skew the charts and mar the chart scale.
AFAIK, ubuntu 11.10 can not boot from a btrfs partition without having the /boot on a ext2/3/4 partition.
Also, for future BTRFS articles, can you give a small tutorial on how to set up a btrfs compressed partition during install? i am a linux noob and cant find any good tutorial for this.

Nice test. Please test the same on a traditional HDD, that would offer a much more complete image, I think.
Yes agreed entirely. I haven't found any reason yet to go SSD, I prefer the extra storage and don't like the extra cost. That and linux is much friendlier on disk access than windows is.

Just remember to learn how to align your partitions and choose your fstab options correctly (link), as all that stuff doesn't work automatically yet and it makes a huge difference in performance.
I bought a SSD in 2010. Once you go there, you can't go back.

MLC vs SLC
Yes, there are "cheap" SSD disks nowadays, but they use MLC chips, that are slower and have a short life (short number or writes before fail). In 2 or 3 years you could have problems with a SSD MLC disk. SLC have a much longer life (large number or writes before fail) and are a lot quicker, but they are much more costly per Gb. http://en.wikipedia.org/wiki/Multi-level_cell
True, but what I was hinting at, is that the best FS for SSD might not be the best for HDD as well. So you might need to mix and match, if Michael is kind enough to provide us with the data.

I recall a several year old balanced server IDF topic in which an Intel guy noted that md5 software raid 5 requires lots of memory bandwidth. Did they do better?
Raid is not something you'd want to do with SSDs. You lose TRIM.
