RAID 0 vs. RAID 1: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 30, 2024
RAID 0 focuses on performance by striping data across disks, no redundancy; RAID 1 offers data redundancy by mirroring data across two or more disks.

Key Differences

RAID 0, known for its performance enhancement, distributes data across multiple disks in a method called striping, which significantly speeds up data access. In contrast, RAID 1 is designed for redundancy, mirroring data identically on two or more disks, prioritizing data safety over speed.

In RAID 0, data is split into blocks and each block is written to a separate disk, enabling high-speed data processing and large storage capacity. RAID 1, however, stores an exact copy of the data on all disks, which reduces the total storage capacity to the size of one disk but ensures data is not lost if one disk fails.

With RAID 0, if one disk fails, all data in the array is lost, as the data is spread across all disks without redundancy. RAID 1, in contrast, can withstand the failure of one disk (in a two-disk setup) since the other disk holds an exact copy of the data, allowing for continued operation and easy data recovery.

RAID 0 is ideal for environments where high-speed data access and maximum storage are critical, like in gaming or video editing. RAID 1, on the other hand, is best suited for critical data storage, like in servers or for individuals who prioritize data security, due to its mirroring feature.

The cost-efficiency of RAID 0 is seen in its full utilization of all disk space, but at the risk of data loss. RAID 1's cost lies in the duplication of disks for redundancy, making it less space-efficient but highly reliable for data protection.
