I have a question about the difference between RAID 10 and RAID 01, believe me, I did all the research I can, and read all the technical terms like stripped mirrors or mirrored stripes, but I can't really find exactly why a scenario would prefer one of the two. I think what I really need is an explanation in english.
I have a datawarehouse project next month and the database size gets to over 500GB. I need exceptional IO performance hence I choose this RAID setup over the RAID 1/0/5.
Also, can someone tell me how is the IO overhead comparison between 5 and 10?
