    P55 RAID 0 Write-Back Cache Slows Down Writes

    Stubi

      I have a GA-P55-UD6 board and 3 1TB disks in RAID 0.

       

      When I switch on the write-back cache the writes slow down significantly. Below a test with Cristal Disk Mark. Other tools show similar results. Why is it like this and what is this cache good for if it slows down the writes? Here the right picture shows the results with write-back cache:
