text: **3.9 Internal storage configuration**
  
  For general-purpose storage pools with various I/O applications, use the storage 
  configuration wizard in the GUI. For specific applications with known I/O patterns, use CLI to 
  create arrays that suits your needs. 
  
  Use DRAID 6 as the default RAID level for internal arrays. DRAID 6 outperforms RAID 5. 
  Workloads that used to be placed on RAID 10 arrays now are usually on SSD drives.
