The eight data disks, where I do the testing, are combined to a software raid 1+0 (not Raid 10). Because I am using software raid barriers are disabled, so for all testing barriers where disabled. The mount options are: noatime,nodiratime,commit=15 There are also a 4 port and a 2 port Gigabit network card, but these where not used.
