Alibaba Cloud Storage Pricing Comparison 2026: OSS vs. NAS vs. Tablestore & Optimization Strategies

Storage is often the fastest-growing line item in cloud bills. Understanding the different storage options and choosing the right one for each use case can reduce storage costs by 50%–80%. This guide compares Alibaba Cloud's three main storage services — Object Storage Service (OSS), Network Attached Storage (NAS), and Tablestore — covering pricing, use cases, and proven optimization strategies.

1. Storage Services Overview

Object Storage Service (OSS)

OSS is Alibaba Cloud's massively scalable object storage service. It stores data as objects in buckets, accessible via HTTP/HTTPS API. OSS is ideal for unstructured data like images, videos, backups, logs, and static website content.

Network Attached Storage (NAS)

NAS provides shared file storage accessible via standard file protocols (NFS, SMB). Multiple ECS instances can mount the same NAS volume simultaneously. It's perfect for shared content repositories, home directories, and container persistent volumes.

Tablestore

Tablestore is a serverless NoSQL database service designed for structured and semi-structured data. It provides automatic scaling, single-digit millisecond latency, and supports both key-value and wide-column data models.

2. Pricing Comparison

2.1 OSS Storage Pricing (Singapore region)

Storage Class	Price per GB/month	Minimum Storage Duration	Data Retrieval Fee	Best For
Standard	$0.0200	None	Free	Frequently accessed data, websites, media
Infrequent Access	$0.0100	30 days	$0.01/GB	Accessed 1–2 times/month
Archive	$0.0033	60 days	$0.02/GB + wait time	Long-term backup, compliance archives
Cold Archive	$0.0010	180 days	$0.03/GB + longer wait	Regulatory archives, rarely accessed

Additional OSS costs: Request fees (GET/PUT operations), data transfer fees, and optional features like data processing, transfer acceleration, and replication.

2.2 NAS Pricing

NAS Type	Price per GB/month	Performance Level	Protocol	Best For
Capacity NAS	$0.06 – $0.09	Standard	NFS/SMB	General file sharing, backups
Performance NAS	$0.18 – $0.24	High IOPS	NFS/SMB	Databases, high-performance apps
Extreme NAS	$0.30 – $0.40	Extreme IOPS	NFS	HPC, enterprise applications

2.3 Tablestore Pricing

Pricing Component	Cost	Notes
Data storage	$0.012/GB/month	Reserved and actual used space
Read capacity units (RCU)	$0.00012 per unit/hr	4 KB read unit
Write capacity units (WCU)	$0.00024 per unit/hr	4 KB write unit
Pay-as-you-go reads	$0.0015 per 10,000 reads	Flexible capacity mode
Pay-as-you-go writes	$0.0060 per 10,000 writes	Flexible capacity mode

3. Use Case Decision Tree

Choosing the right storage service for each workload is the first step toward cost optimization:

If you need…	Choose…	Why
Storing images, videos, documents	OSS Standard	Lowest cost per GB for unstructured data
Shared file system across servers	NAS Capacity	POSIX-compliant, easy to mount
Website static assets & media	OSS + CDN	Fast global delivery, low cost
Backup & disaster recovery	OSS Archive / Cold Archive	Extremely low cost for long-term storage
IoT sensor data, time series	Tablestore	Serverless, auto-scaling, low latency
High-performance database	NAS Performance / ESSD	High IOPS, consistent performance
Log storage & analysis	OSS Infrequent Access + SLS	Cost-effective for large log volumes
Container persistent volumes	NAS or Cloud Disk	Depends on access pattern

4. Cost Optimization Strategies

4.1 Implement Lifecycle Policies

This is the single most impactful optimization for OSS. Automatically transition data through storage tiers based on age:

• Day 0–30: Standard (frequent access)
• Day 30–90: Infrequent Access (50% savings)
• Day 90–365: Archive (83% savings vs standard)
• Day 365+: Cold Archive (95% savings vs standard)

A well-designed lifecycle policy can reduce long-term storage costs by 70%–90% without data loss.

4.2 Enable Compression & Deduplication

Text-heavy data (logs, documents) typically compresses 3:1 to 10:1. Enable server-side compression or compress data before upload. Use client-side deduplication for backup workloads.

4.3 Delete Stale & Orphaned Data

Most organizations have 20%–40% of storage consumed by data that's truly obsolete — old test data, forgotten backups, duplicate files. Run periodic storage audits and set up expiration rules for temporary data.

4.4 Use Intelligent Tiering

OSS Intelligent Tiering monitors access patterns and automatically moves data between tiers. There's a small monitoring fee but no retrieval fees when data moves between frequent and infrequent tiers. Great for workloads with unpredictable access patterns.

4.5 Optimize Data Transfer Costs

Data transfer between Alibaba Cloud services within the same region is free. Use:

• Internal endpoints for cross-service access
• CDN for content delivery (cheaper than direct OSS egress at scale)
• Data Transport Service for large data migrations

4.6 Right-Size Provisioned Capacity

For Tablestore and provisioned NAS, review actual usage and adjust provisioned capacity downward if you're consistently under-utilizing. Many teams provision for peak and forget to scale down.

5. Real-World Cost Reduction Examples

Example 1: Media Company

A media company with 500 TB of video files reduced storage costs by 65% by implementing lifecycle policies: new videos stay in Standard for 30 days (active views), move to Infrequent Access for days 30–90, then Archive for long-tail content.

Example 2: SaaS Company

A SaaS startup cut log storage costs by 80% by storing 7 days of logs in Standard OSS, 30 days in Infrequent Access, and archiving the rest. They also reduced data transfer costs by 40% using CDN for static assets.

Example 3: Enterprise IT

A 2,000-person enterprise reduced NAS costs by 40% by moving home directories and shared documents from Performance NAS to Capacity NAS, reserving Performance NAS only for application workloads that actually need high IOPS.
