Phoronix: Large HDD/SSD Linux 2.6.38 File-System Comparison

Here are the results from our largest Linux file-system comparison to date. Using the soon-to-be-released Linux 2.6.38 kernel, on a SATA hard drive and solid-state drive, we benchmarked seven file-systems on each drive with the latest kernel code as of this past weekend. The tested file-systems include EXT3, EXT4, Btrfs, XFS, JFS, ReiserFS, and NILFS2.
