Linux supports software-based drive arrays, which can be configured through the mdadm utility. Most of the array options are designed to provide some level of data redundancy, but the exact benefits and trade-offs vary.
This RAID 1 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 array will re-duplicate the files. Configuring this option requires two 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.
