Which RAID for Data Warehouse

Helou Guys, at the first place, if I'm asking in bad Category Forum, just correct me, thanks and sry.

Second, if someone can tell me, which RAID is best for Data warehouse for best read performance? I've red some articles and many times is suggested RAID5. I would rather build RAID50 (2 times RAID5 then RAID0) or RAID 10. Can someone help me solve this problem, which RAID is best for datawarehouse? (Have no experience.... :/)

Data warehouse will run on server with 8 disks (SSD) for now. If SSD is not necessary, I can change them for 10K or 15k disks.

Thanks for help.
