EXT4 vs. XFS vs. Btrfs HDD Benchmarks On Linux 3.15

Running AIO-Stress on the Western Digital VelociRaptor was yielding speeds not technically possible for the Serial ATA 3.0 hard drive when using EXT4 and XFS. There was obviously some caching / lack of committing to disk involved that led to faster performance while the Btrfs file-system was in line with real-world expectations out of the random write disk test.

When running Dbench with one instance, the XFS file-system ran much faster than EXT4 and Btrfs.

While XFS led when just one Dbench instance was active, when running six Dbench instances the Btrfs file-system lept out ahead of EXT4 and XFS.
