Which description best fits RAID 0?

RAID 0 is characterized primarily by its use of data striping. In this configuration, data is split into blocks and written across multiple drives, enhancing performance by allowing simultaneous read and write operations. It does not incorporate any mirroring or parity, meaning there is no redundancy. This configuration provides better performance compared to a single drive setup, as data can be accessed from multiple drives at once.

Choosing this option reflects an understanding that the primary advantage of RAID 0 lies in speed, without the additional complexity or overhead associated with redundancy that other RAID levels might offer. The other choices imply the presence of redundancy features (like mirroring and parity) which RAID 0 distinctly lacks, focusing solely on performance enhancement through striping.
