The technology that requires multiple storage disks to access data efficiently without using RAID is JBOD, which stands for "Just a Bunch Of Disks." In a JBOD configuration, multiple disks are connected and managed as separate entities, allowing for straightforward data access across those disks. This setup does not strip or mirror data like RAID configurations do, so each disk operates independently.

Using JBOD allows for a simple and effective way to increase storage capacity without the overhead and complexity of RAID management. It is important to note that while JBOD improves access efficiency by distributing data across multiple disks, it does not provide the redundancy or performance benefits associated with RAID systems.

In contrast, other options such as Independent Storage Networks, Cloud Storage, and Network Attached Storage do utilize different mechanisms for data access and redundancy, often involving RAID configurations to enhance performance or reliability, making them less aligned with the context of the question.
