The reason to use raid 1 was to have the data rescued before the backup. In a hardware raid setup, the drives connect to a raid controller card inserted in a fast pciexpress pcie slot in a motherboard. You may understand the data organization of the 2 raid arrays from the following picture. Raid 1, on the other hand, offers a safety net in the form of data redundancy. Or you could set up raid 01 with a 3 disk raid 0 stripe set on each controller, and a software raid 1. On the behalf of redundant array of independent disks, raid is a technology for better performance and reliability of data storage by incorporating multiple hard drives to work in parallel. According to different needs, the raid level can range among raid 0, raid 1, raid 5, raid 10 and more. Raid 0 simply means stripping of data whereas raid 1 is data mirroring, in raid 0 data is stored in one place whereas in raid 1 it can be stored in stripes at multiple places. Of those that offer redundancy, raid1 and raid5 are the most popular. Raid level, raid 0, raid 1, raid 4, raid 5, raid 6, raid 10. Understanding raid performance at various levels storagecraft. Raid 0 and raid 1 place the lowest overhead on software raid, but adding the parity calculations present in other raid levels is likely to create a bigger impact on performance. Raid 5 also offers fault tolerance but distributes data by striping it across multiple disks. Of course, raid 1 requires a great deal of extra disk space double the usable space you need, so you pay for each approach in different ways.
It also matters whether you have hardware or software raid, because software supports fewer.
