    * Which RAID setup for high IOWAIT problems

    Let's say the HDDs of the server are 2 250GB SATA Hard Drive at 7.2K RPM

    which of these two RAID options would reduce high IOWAIT problems

    Hardware Raid 1 - Mirroring

    Hardware Raid 0 - Striping

    Thanks in advance

    For performance alone, RAID 0.
