Thanks for your response. Do you mean 1 SSD for OS and 3 journal + 4 SAS
900G  + 5 free slots ? I had in mind the OS in RAID 1, but with 2 cheap 
SSD intel 3500 disks. The OS disk are SSD, but not for gaining
performance, they are only 100G and they are cheap. I though that a OS
failure could be worst than a journal or a single OSD failure, because
the recovery time to restore de OS could be higher.
