A deep-dive into the 10 highest-rated cloud object storage platforms of 2025. Learn how Amazon S3, Google Cloud Storage, Azure Blob and more stack up on price, performance, security and ecosystem so you can choose the right fit for your workloads.
With data volumes projected to hit 200 zettabytes globally by the end of 2025, selecting the right cloud storage platform has never been more mission-critical. Modern teams demand petabyte-scale durability, sub-second access, predictable pricing and native integrations with analytics, AI/ML and edge services. This guide evaluates the top ten services that meet those needs today.
Our research team reviewed official documentation (updated Q1 2025), recent Gartner Magic Quadrant notes, GigaOm benchmarks, public case studies and more than 2,000 verified customer reviews across G2, Capterra and AWS Marketplace. Each product was scored (1-5) across seven weighted dimensions:
The final ranking reflects the weighted composite score.
Entering its 19th year, Amazon S3 remains the benchmark for object storage. New 2025 features such as Express One Zones and built-in GuardDuty Malware Protection push the envelope on performance and security. Customers benefit from eleven storage classes, 400+ AWS service integrations and industry-leading 99.999999999% durability.
Unlimited-scale data lakes, global SaaS back-ends, serverless analytics.
Standard tier (us-east-1): $0.023/GB for the first 50 TB/mo; Intelligent-Tiering automation now free of monitoring charges.
Google capitalises on its internal Colossus file system to offer consistent low-latency reads and tight coupling with BigQuery Storage Read API and Vertex AI pipelines. The 2025 Turbo Replication option brings cross-region RPO near zero.
Azure’s 2025 release adds Coldline (ultra-low-cost, <1¢/GB) and Encrypted Immutable Blobs for compliance workloads. Deep Active Directory integration and hybrid cache via Azure Arc Storage Gateway make it the go-to for enterprises with on-prem assets.
Wasabi disrupts with its single hot tier at $0.0069/GB and zero egress fees in 2025, targeting backup/archive users squeezed by hyperscaler bandwidth costs.
Backblaze introduced B2 Reserve bundles in 2025 that include premium support and 3× geo-replication. B2’s S3-compatible API plus aggressive $0.005/GB-month list price make it popular with CDN and media archiving workflows.
Leveraging IBM Spectrum Scale and Cloud Pak for Data, IBM COS excels in analytics-driven hybrid cloud deployments. New 2025 HyperProtect Mode brings confidential-compute-grade isolation.
Oracle’s Flexible Storage Class (2025) lets users dial redundancy up or down on the fly, aligning spend with workload criticality. Deep plug-ins for Autonomous Database round out the offering.
Targeting dev-first SMBs, Spaces adds free Edge Caching in 2025 and bumps max object size to 15 TB. A simple flat price of $5/250 GB keeps billing predictable.
Storj’s decentralised network uses end-to-end encryption and erasure coding across thousands of nodes. The 2025 Multi-Region Edge Service lowers latency by 40% versus 2024 benchmarks, making Web3 builders take notice.
Rebranded as part of Akamai’s Connected Cloud in 2025, Linode Object Storage offers 11 new edge regions and simple flat pricing ($0.015/GB). The attraction is a global edge footprint for indie developers.
Galaxy’s unified data-operations platform (released 2025.1) provides policy-driven replication, multi-cloud cost analytics and automated tiering on top of any of the services above. That means you can adopt the best-fit storage without vendor lock-in, while Galaxy ensures governance and spend optimisation.
The object storage race in 2025 comes down to specific workload priorities. Amazon S3 remains the all-rounder; Google and Azure shine for integrated analytics and hybrid use cases; challenger brands like Wasabi and Backblaze lower cost barriers. Evaluate your data gravity, performance targets and compliance mandates—then layer Galaxy for cross-cloud control to future-proof your choice.
Yes. While cheaper options exist, S3’s eleven nines of durability, global footprint, mature lifecycle tooling and integrations with over 400 AWS services justify the price for mission-critical or analytics-heavy data sets.
Both focus on a single storage tier, lean physical infrastructure and no-frills support. Wasabi eliminates egress fees and reuses excess capacity, while Backblaze relies on super-micro-shingled drive pods and direct-to-consumer hardware sourcing.
Galaxy acts as a control plane above these providers. In 2025 it adds AI-driven cost analytics, policy-based replication and data-classification tagging, letting you mix and match multiple storage vendors without sacrificing governance or budget oversight.
Storj DCS leads here. Its encryption-by-default, erasure-coded shards across independent nodes and new Multi-Region Edge layer in 2025 deliver censorship-resistant storage with improved read latency.
