what are your trying to acomplish? each raid set up is designed to have it own individual strengths. i am familar with raid0 and raid 1, bot further than that, i dont know a whole lot. i would suggest look at Wikipedia.com.
ok i already did the search for you.

for the home user id do not see a need for anything other than raid0, or raid1. only if you are trying to experiment around, and see what kind of preformance that you can get, but unless you are using a huge amount of Hdd space all the time, i dont see any noticable bennifit.
for a business, or a college server, that might be quite a bit differance, but for simple home operations, i dont see this being necessary any time soon in the future
