Inspecting disk IO performance with fio

You ought to try Linux RAID 10. It's not RAID 1+0, but a new type of array unique to Linux. It's more expensive for disks, but it's very fast reads and writes, and far more reliable than RAID 5, which in my experience is not reliable at all. This article http://www.enterprisenetworkingplanet.com/nethub/article.php/3730176 has some good information, and so does the Linux RAID mailing list, though I warn you- some of the regulars are grumpy old bastards who expect you to already know everything, even though RAID 10 is fairly new and almost completely undocumented. http://marc.info/?l=linux-raid
