8. Select all hard drive members of the RAID volume, and then click the right arrow to place all three hard drives in the Selected box. 9. Click Next. 10. Complete the volume size selection screen, and then click Next. NOTE: If users consume all available storage for this RAID volume, there will be no space to create another RAID volume for this hard drive, thereby not allowing for Matrix mode RAID. Note the size if you want to create a second RAID volume in this set of hard drives. 11. To create one RAID 0 out of the hard drive, leave the default of 100% for Percentage of Available Space, and then click Next. 27
