Ah, okay, I assumed that because you had a 9211-8i, you had SATA3 disks, I wondered why you had it, do you think that a SAS3081E-R differs that much from a 9211-8i, driving 8x disks, as it's only SATA 2? What models of Samsungs disks are you using? What OS? (FreeNAS ZFS?) I be interested in your bonnie speeds?
