I thought about modding parent up for mentioning the downside to RAID5 with modern hard drives but it was an AC with a score of 0 so most still wouldn't have read it.
So I'll just do it myself and link to http://www.baarf.com/
I still don't understand why so many people use RAID 5 when disks and controllers are cheap enought to do RAID 10 or multiple RAID 1 arrays instead. And if you are using enough data that RAID 10 doesn't do it for you then RAID 6 might be a OK solution but I wouldn't recommend any RAID solution unconditionally.
I will unconditionally recommend against RAID 5 though. And in a similar train of though I'll conditionally recommend against RAID 0 (though it does have valid uses it's often used by those that don't understand the down sides).
