Further evidence to dispel the myth that RAID is a performance solution.

I did some annecdotal measurements a few years ago comparing a 7200RPM IDE
disc to a hardware RAID 5 using 10K RPM SCSI drives. The single IDE disc
consistently out performed the RAID. The same RAID hardware performed much
better running Linux (2.4 kernel) than Windows 2000 but not as good as the
single disc.
