Why is RAID 1 a good choice for a customer with two HDDs?

RAID 1 is an excellent choice for a customer with two hard disk drives (HDDs) primarily because it provides excellent data redundancy and fault tolerance. In a RAID 1 configuration, data is mirrored across both drives. This means that every piece of data is written identically to both HDDs, which ensures that if one drive fails, the other drive still holds a complete, intact copy of the data. This redundancy is crucial for maintaining data integrity and availability, especially in environments where data loss can lead to significant issues.

Moreover, RAID 1 allows for continuous operation even in the event of a hardware failure. This level of fault tolerance is particularly important for businesses that cannot afford downtime or data loss. In terms of recovery, RAID 1 simplifies the process because the data can be quickly accessed from the surviving drive should one fail.

While other options might mention aspects of storage or performance, they do not provide the strong data protection that RAID 1 offers, making it the most suitable configuration for scenarios where reliability and data safety are prioritized.
