What is RAID?
Your NAS protects your data in a variety of ways. One of the biggest ways is using RAID technology. RAID uses redundancy to protect the data in your NAS from hard drive failure. RAID takes hard drives and uses the capacity of at least one of your hard drives to store redundant information. This redundant information helps protect and rebuild the volume when a hard drive fails. ASUSTOR NAS devices also support RAID 0, which can be used to combine all drives into one single large volume. It should be mentioned that RAID is not a backup. Instead, it is a powerful tool for data protection and makes part of a holistic solution for protecting your data.
