2. RAID Coniguration RAID Coniguration Precautions 1. Before creating a RAID array, please check the user manual for information of what levels of RAID does your motherboard support, which SATA ports support RAID and other related requirements. 2. Please use two new drives if you are creating a RAID 0 (striping) array for performance. It is recommended to use two SATA drives of the same size. If you use two drives of different sizes, the smaller capacity hard disk will be the base storage size for each drive. 3. You may use two new drives, or use an existing drive and a new drive to create a RAID 1 (mir- roring) array for data protection (the new drive must be of the same size or larger than the existing drive). If you use two drives of different sizes, the smaller capacity hard disk will be the base storage size. 4. Please verify the status of your hard disks be- fore you set up your new RAID array. 5. Please backup your data irst before you cre�- ate RAID functions. In the process you create RAID, the system will ask if you want to "Clear Disk Data" or not. It is recommended to select "Yes", and then your future data building will operate under a clean environment. 3
