# S3 Express One Zone Bucket

S3 Express One Zone Bucket is a high-performance Amazon S3 storage option designed for workloads that need very low latency and high request rates. Data is stored in a single Availability Zone, making it cost-effective compared to multi-zone storage, but with less redundancy. It is ideal for applications that require fast access to frequently changing data, such as analytics or machine learning, where durability across multiple zones is not critical.
