What is the benefit of using cloud storage in conjunction with a RAID array?

1. Increases image resolution

2. Improves printing quality

3. Provides additional backup in case of drive failure

4. Enhances display color accuracy

The correct answer is: Provides additional backup in case of drive failure

Using cloud storage in conjunction with a RAID array offers the significant advantage of providing additional backup in case of drive failure. While a RAID (Redundant Array of Independent Disks) array enhances data redundancy and performance by spreading data across multiple disks, it does not protect against all types of data loss. For example, if a RAID array experiences simultaneous failures of multiple drives, or if there's a catastrophic event such as theft, fire, or natural disaster affecting the physical location of the drives, the data could be lost. Incorporating cloud storage as part of a backup strategy ensures that critical data is stored off-site and can be accessed remotely. This provides an extra layer of security, as data residing in the cloud is typically replicated across multiple servers in different geographic locations. Thus, should the RAID array fail, having cloud storage means the photographer can restore their valuable images from the cloud, minimizing the risk of permanent data loss. The other choices involve aspects that, while important in their own rights, do not directly relate to the primary function of backup and data protection provided through cloud storage combined with RAID systems.
