The disk layout for the four test was in RAID1 or RAID10 mode over

1. two disks with write-back cache policy (iozone-local)
2. two disks with write-through cache policy (iozone-data)
3. four disks in RAID10/write back policy (iozone-data2)
4. eight disks in RAID10/write back policy (iozone-data3)

Results (output are all in IO/s). Each column appears twice as we upgraded the firmware of the Areca controller to a much later version which should increase RAID10 speeds. First column of each type is with the old v1.46 and v1.47 is on the right.
