It’s much more effective in achieving optimal capacity and redundancy. This sets up the RAID again without losing data in most cases. If one hard drive fails, most of the time you can take it out and replace it with a new one. This is a handy setup to have if you can’t have your computer go down for any reason. This creates a complete backup down to the last bit of data. Known as mirroring, this RAID achieves redundancy and data security by continuously replicating or cloning data across two hard drives. Repairing RAID 0 can be done at the individual drive level. Usually, RAID 0 is not recommended for those seeking data security due to its lack of redundancy. This is great for users who are seeking high capacities and faster performance. Let’s take a look at the different RAID Arrays for Mac and look into how they work. There are five different RAID levels with each of them having its own use case. Your computer then sees these hard drives as one drive, instead of each individually.
In the simplest terms, a Redundant Array of Inexpensive Disks or RAID, is a collection of physical hard drives that have been linked together.
