S3 Express One Zone targets workloads requiring fast, consistent, single-digit millisecond data access, including machine learning training and interactive analytics. Compared to S3 Standard, it provides up to 10 times faster access speed and up to 80% reduction in request costs, though with single-zone durability tradeoffs.
The expansion brings availability to 15 AWS regions globally, enabling more customers to leverage its performance benefits within their chosen geography. AWS positions this storage class as suitable for workloads tolerant of a single Availability Zone failure but demanding high performance and cost efficiency.
