Benchmarking hardware RAID vs. Linux kernel software RAID
,----[ Quote ]
| My tests showed that the choice of filesystem makes a huge impact on
| performance, with XFS being substantially quicker for output on parity RAIDs,
| though in some configurations, such as 256KB-chunk RAID-10 block input, XFS
| can be slower than ext3.
