ReadyNAS OS 6.1 Table 3. Flex-RAID levels and data protection Number of Disks RAID per Volume Level Can I add a disk to for data protection? 1 RAID 1 Yes. (Additional disk provides redundancy.) 2 RAID 1 No. (Volume protection is already redundant.) 2 or more RAID 0 No. (RAID 0 does not offer protection.) 3 or more RAID 5 Yes. (Additional disk provides dual redundancy and converts the volume to RAID 6.) 4 or more (even number) RAID 10 No. (Volume protection is already redundant.) 4 or more RAID 6 No. (Volume is already protected with dual redundancy.) Disks added to a Flex-RAID volume can be used only for protection. They cannot be used for storage (horizontal expansion). If you want to add a disk for increased storage capacity, you must do one of the following: • Create a volume using the added disks (see Create and Encrypt a Volume on page 29). • Change the RAID level (see Change to a Different Flex-RAID Level on page 25). • Switch to X-RAID2 (see Change from Flex-RAID to X-RAID2 on page 24). To add a protection to a Flex-RAID volume: 1. Add a disk to your ReadyNAS storage system. For more information about how to add a disk to your system, see the hardware manual for your system, which is available at http://support.netgear.com/product/ReadyNAS-OS6. 2. Select System > Volumes. The new disk is displayed in the enclosure graphic and is colored black. 3. Select the new disk from the enclosure graphic. Volume Configuration 35
