Understanding RAID 5 Recovery As the name implies, RAID is a method of joining multiple hard drives together to form one large very fast virtual disk drive AND it’s designed so if any one hard drive fails, the integrity of the data will remain intact. This is accomplished by using one drive or stripe, for parity.
