Object Storage. Simplified.

SDX (Storage Data eXchange) redefines object storage with massive file support, resumable uploads. Starting at just $0.023/GB.

DDoS Protected
Up to 1TB Single File
Why SDX Crushes Traditional Object Storage

Built Different. Built Better.

We didn't just create another S3 clone. SDX is engineered from the ground up to solve real problems developers face every day with massive files, interrupted uploads, and complex data workflows.

Upload Files Up To 1TB in One Go

Stop worrying about file size limits. SDX handles terabyte-scale uploads with intelligent multipart chunking and automatic optimization.

Resumable Uploads That Actually Work

Network dropped? No problem. Resume exactly where you left off without starting over. Perfect for unstable connections or massive datasets.

Smart Data Replication & Distribution

Replicate data across multiple SDX buckets automatically. Build geo-redundant storage architectures with zero manual intervention.

Sub-Buckets: Organization Made Simple

Create unlimited nested folder structures (sub-buckets) to organize your data exactly how you need it. No more flat namespace headaches.

Enterprise-Grade DDoS Protection

Your storage is protected by Cloudflare's network, ensuring your data remains accessible even during massive attacks.

Frequently Asked Questions

Everything You Need to Know

How does SDX handle file uploads over 1TB?

While SDX supports up to 1TB single file uploads, you can store files of any size by using our intelligent chunking system. Files are automatically split, uploaded in parallel, and reassembled transparently.

Is SDX compatible with S3 tools?

Yes! SDX provides an S3-compatible API, meaning you can use existing S3 SDKs, CLI tools, and applications with minimal modifications. Migration from S3 is straightforward.

What happens if my upload is interrupted?

SDX's resumable upload feature automatically saves your progress. When you reconnect, the upload continues from where it stopped—no data is lost, and you don't start over.

How does data replication work?

You can configure automatic replication between SDX buckets. Data is copied asynchronously to your specified destinations, providing geo-redundancy and disaster recovery capabilities.

Are there any hidden costs?

No. You pay only for storage, bandwidth, and API requests. There are no setup fees, minimum commitments, or surprise charges. DDoS protection via Cloudflare is included at no extra cost.

Can I use SDX for production workloads?

Absolutely! SDX is built for production with 99.9% uptime SLA, enterprise-grade security, automatic redundancy, and 24/7 monitoring. Thousands of applications rely on SDX daily.
