Why each option
RAID 0 provides high read/write performance by parallelizing I/O across all drives but offers zero fault tolerance.
RAID 0 has no fault tolerance - losing even one drive destroys the entire array, making it the least fault-tolerant RAID level.
Recovery from a drive failure is impossible in RAID 0 without a separate backup, since there is no parity or mirrored copy to rebuild from.
Because RAID 0 stripes data across multiple drives simultaneously, read and write operations can be performed in parallel across all drives, multiplying throughput relative to a single drive. This performance gain is the sole functional benefit of RAID 0, as there is no redundancy of any kind.
RAID 0 requires deliberate configuration to establish striping across drives and does not function automatically without setup.
