A company has a video editing application that requires consistent sub-millisecond latency and high throughput...

S3 Express One Zone is designed for latency-sensitive workloads that need high request rates and very fast access to objects within a single Availability Zone. It uses S3 directory buckets and maintains S3 API compatibility, which directly matches the requirement to improve performance without moving away from the S3 API model. The media objects are updated frequently and require consistent low latency, so S3 One Zone-IA is not appropriate because it is intended for infrequently accessed data. S3 Transfer Acceleration improves long-distance upload and download performance but does not provide single-AZ, low-latency object access for active editing. S3 table buckets are built for tabular analytics, not frequently updated media object workloads.
