RustFS
RustFS is a high-performance, S3-compatible object storage system built in Rust. It is 2.3x faster than MinIO for small object payloads and offers full S3 API compatibility, a built-in web management console, erasure coding with Reed-Solomon for data protection, bitrot detection via HighwayHash, and server-side encryption with AES-256-GCM and ChaCha20-Poly1305. RustFS supports event notifications, bucket versioning, object lifecycle management, bucket replication, and CORS configuration. Licensed under the permissive Apache 2.0 license, it is designed for data lakes, AI workloads, and large-scale storage with a user-friendly deployment experience.
SeaweedFS
SeaweedFS is a fast, simple, and highly scalable distributed file system for storing and serving billions of files. Starting as an object store with O(1) disk seek performance, it has grown into a full-featured storage platform supporting S3 API, WebDAV, FUSE mount, HDFS, and Hadoop integration. The architecture separates concerns into a master server for volume management, a volume server for blob storage, a filer for directory/file abstraction, an S3 gateway for S3 compatibility, and a WebDAV server for mounted drive access. Features include erasure coding, cloud tiering, cross-datacenter replication, AES-256-GCM encryption, automatic compaction, file TTL, and a built-in admin UI.
