Our verdict on UCloud US3
UCloud US3 is a cloud object storage service for internet applications, with browser, HTTP REST API, SDK, command-line, and console access. It is aimed at teams storing application data, backups, media, analytics, AI workloads, and enterprise or government data. Unlimited storage capacity and individual files up to 5 TB make it suitable for large unstructured-data repositories, while Standard, Infrequent Access, and Archive tiers cover different access patterns.
Pricing is billed daily per GB rather than through monthly plans. Standard costs $0.00063 per GB per day and includes real-time access, 99.999999999% data durability, and 99.95% availability. Infrequent Access costs $0.00031 per GB per day, with the same durability and 99.9% availability. Archive is priced at $0.00013 per GB per day for long-term archive storage, with 99.999999999% durability and 99.9% availability. The published pricing varies by storage tier and region, so US3 suits buyers who can match access needs to a daily storage tier.
AWS S3 API compatibility gives existing S3-oriented applications a direct integration path, and US3 also connects with UCloud CDN, image processing, video streaming, and UHost private networks. Multipart uploads and resumable downloads support large transfers, while cross-region replication adds a geographic data-management option. UCloud lists ISO 27001 and offers 24/7 support through email, tickets, and documentation. Choose US3 when low daily storage rates, large objects, S3 access, and media integrations matter. Buyers needing a free plan, monthly plan presentation, or stronger availability on lower-cost tiers should compare alternatives.
