  2. Click Manage and then select Expand.

  3. Click OK.
  4. Select one or more SSDs.
    Warning:

    All data on the selected disks will be deleted.

  5. Select a RAID type.
    Warning:

    Selecting a RAID type with no disk failure protection (Single, JBOD, RAID 0) when the cache type is Write-only or Read-write may result in data loss.

    Tip:

    RAID 10 provides the best write cache performance.
