How is RAID 1 different from RAID 0?

RAID 1 is designed specifically for redundancy, enhancing data protection by duplicating the same data across multiple drives. This mirroring process ensures that if one drive fails, the data remains accessible from the other drive, thus safeguarding against data loss. This characteristic makes RAID 1 an ideal choice for environments where data integrity and availability are paramount.

On the other hand, RAID 0 is focused on performance and speed. It does this by striping data across two or more drives, allowing for faster read and write operations since multiple disks can be accessed simultaneously. However, RAID 0 does not provide redundancy; if one drive fails, all data in the array is lost.

The other options describe characteristics that do not correctly differentiate RAID 1 from RAID 0. For instance, while RAID 1 does require more than one drive to function due to its mirroring nature, it does not operate with just one drive; this idea negates the fundamental design of RAID 1. Regarding the interaction of data, RAID 0 stripes data for performance enhancement, and RAID 1 mirrors it, focusing on redundancy instead. Thus, the key differentiator lies in RAID 1's focus on ensuring data protection through redundancy, contrasted with RAID 0's emphasis on
