An administrator needs to set up a RAID which requires high performance but no data protection. Which RAID level fulfills these requirements?

RAID 0 is designed to provide high performance by distributing data across multiple disks in a process known as striping. This means that data is split into blocks and written across multiple drives, allowing for simultaneous read and write operations. As a result, this configuration can significantly enhance speed and throughput, making it ideal for applications where performance is critical, such as video editing or gaming.

However, it's important to note that RAID 0 does not offer any data protection or redundancy. If one drive in the array fails, all data in the RAID 0 configuration is lost. This lack of protection is acceptable in scenarios where the primary need is performance, and data redundancy is not a concern.

The other RAID levels mentioned provide varying degrees of performance along with data protection. For instance, RAID 1 mirrors data across two drives, offering redundancy but sacrificing some performance. RAID 5 and RAID 6 both use distributed parity for redundancy, which can impact write performance compared to RAID 0. Thus, for the requirement of high performance without a need for data protection, RAID 0 is the appropriate choice.
