Which feature does RAID 0 NOT provide?

RAID 0 is designed to deliver improved speed and performance through a process called striping, which involves dividing data into blocks and spreading it across multiple drives. This setup allows for faster read and write operations, as multiple drives are used simultaneously to handle the workload.

However, one of the key characteristics of RAID 0 is its lack of data redundancy. In RAID 0, if one drive fails, all data across the array is lost because the data is not duplicated or protected in any other drive. This means there is no safeguard against data loss, which is why RAID 0 does not provide data redundancy.

In contrast, other RAID levels, such as RAID 1 or RAID 5, do incorporate redundancy to protect data in the event of a drive failure. Thus, while RAID 0 excels in performance and speed due to its striping feature, it does not offer any form of data redundancy, which is a critical consideration for data protection strategies.
