RAID 5 is more fault tolerant than RAID 0 and RAID 1 because it uses striping with distributed parity, allowing it to withstand the failure of one drive without data loss. In contrast, RAID 0 offers no redundancy, meaning that the failure of any single drive results in total data loss, while RAID 1 provides redundancy through mirroring but requires twice the storage capacity. Therefore, RAID 5 strikes a balance between improved performance and efficient storage utilization while still providing a level of protection against drive failures.
