Get ultra-low latency object storage for performance-critical workloads. AIStor's S3 Express mode eliminates checksum overhead, enables atomic appends, and optimizes LIST operations—all with a simple mode switch, no architecture changes required.
AWS S3 Express One Zone API compatibility for on-premises deployment with full data sovereignty.
Atomic Append Operations
AppendObject API enables sequential writes with offset-based locking—no multipart complexity for log aggregation and streaming ingestion.
UUID-Based ETags
Skip MD5 checksum computation on uploads. Cryptographically random ETags deliver faster PUT throughput while maintaining unique object identification.
Unsorted LIST Operations
Directory buckets return objects without lexicographic sorting, improving throughput for AI training workflows scanning millions of objects.
Sequential Multipart Uploads
Parts must complete in order (1, 2, 3...N) with no gaps—simpler tracking and reduced metadata overhead for large object assembly.
Why AIStor is Different
AWS S3 Express requires special directory bucket types, session-based authentication, and architectural changes to access low-latency performance. Organizations wanting Express-level speed on-premises face a gap—until now. AIStor brings S3 Express capabilities to any deployment with a single flag.
One
Mode Switch
Enable S3 Express deployment-wide—no special bucket types or configuration complexity.
Zero
Extra Auth Steps
Use existing IAM and STS credentials without AWS's session-based authentication overhead.
Full
Erasure Coding
Preserve healing, replication, and data protection while gaining Express performance.
Instant
Rollback Option
Switch between S3 and S3 Express modes with identical IAM policies and zero app changes.
Business Impact
AI/ML Training Acceleration
Unsorted LIST and AppendObject enable faster data enumeration and checkpointing for distributed training.
Simplified Log Aggregation
AppendObject replaces multipart uploads, reducing API calls for high-volume telemetry ingestion.
Faster Analytics Ingest
MD5-free PUTs and unsorted LIST boost throughput for real-time data lake pipelines.
Zero-Risk Testing
Mode switching enables instant S3 vs. S3 Express comparison with identical policies.
