the one and only reason for RAID systems to exist at all is to preserve user data in the event of hardware failure

RAID was developed to ensure of the availability of data in the event of a specific hardware failure, namely a disk failure. Using the in-question-excluded RAID 0 it also can be used to extend the volume size over the capability of a single physical drive.

The data preservation tools are backup and long-term archiving.
