The Lone Wolves weblog has a report on benchmarking Linux filesystems using software RAID
. "As it turns out, my (then) limited understanding of RAID and some trouble with my 3ware RAID cards meant that I had to scale back my benchmark quite a bit. I only have two disks so I was going to test RAID 1. Chunk size is not a factor when using RAID 1 so that axis was dropped from my benchmark. Then I found out that LVM (and the size of the extends it uses) are also not a factor, so I dropped another axis. And to top it off I discovered some nasty problems with 3ware 9550 RAID cards under Linux that quickly made me give up on hardware RAID.
