Storage Spaces is an option in Windows to group multiple drives in order to either have more capacity in a single volume or to add a layer of protection in case of a physical drive failure. Three basic modes are supported: simple, mirror, and parity.
This mirror mode is a basic redundancy option - using half of the total capacity in order to keep copies of all files on two different drives. If one of the drives fails no data is lost, and when replaced the storage space will re-duplicate the files. Configuring this option requires two or more drives and is a great solution for those who want to protect data from physical failures without the complexity of needing more than two drives.
