Introduction At NETGEAR we have received a number of questions regarding X-RAID2™ and FLEX-RAID. This whitepaper is intended to be a simple introduction to the differences between the two options. Before diving in, it is important to understand a few key points: • RAID (Redundant Array of Independent Disks) is a common storage industry term • The primary benefit of RAID is that in multi-disk storage solutions (2-bay or greater) your data is protected against failure of any single disk.

Flex-RAID Flex-RAID architecture has two major advantages: • Support multiple volumes per ReadyNAS. • RAID level can be selected for maximum capacity, redundancy, or performance. The NETGEAR Flex-RAID technology allows you to choose from among several industry-standard RAID levels: • JBOD. This most basic RAID level does not protect your data from loss if one of your drives fails. JBOD is available only on volumes consisting of a single hard disk. • RAID 0.
