The primary benefit of using Object Storage Service (OSS) in Alibaba Cloud is its ability to store unstructured data with high durability. OSS is designed to handle large amounts of data, such as images, videos, backup files, and big data archives, which are typically unstructured. It provides a highly reliable infrastructure that ensures data is stored durably, meaning that the likelihood of data loss is minimized even in the case of hardware failures.

The features of OSS include data redundancy, where data is replicated across multiple locations to enhance durability. This makes it a suitable choice for businesses that require long-term storage solutions for large volumes of unstructured data. Additionally, OSS offers scalability, allowing users to effortlessly increase or decrease their storage needs based on their requirements.

In contrast, reduced latency for critical applications would pertain more to services like Content Delivery Network (CDN) or Elastic Compute Service (ECS) that prioritize fast access times. Automatic scaling of relational databases relates to database management services rather than object storage, and enhanced data encryption capabilities, while important, do not solely define the value proposition of OSS, as many storage solutions offer data protection features. Therefore, the correct focus on OSS's ability to manage unstructured data with high durability clearly delineates its primary
