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.
