In a hybrid scheme, do I need 4 raid partitions on 4 different disks? Which raid level comes first, in other words: should I stripe mirrors or mirror stripes? I think to gain some performance stripes needs to be on different disks, but writes to be parallel also need to go on different disks, so for maximum performance I need 4 disks?
