SeaweedFS is a fast, scalable distributed storage system designed to store and serve billions of files with O(1) disk seek performance, eliminating the need for a central metadata master.

The system includes a blob store with cloud tiering capabilities, and an optional Filer component supporting POSIX, S3 API, FUSE mounts, WebDAV, encryption, and erasure coding for data redundancy. It provides high availability through automatic master failover, multiple replication options, and transparent cloud integration for cost-effective hybrid storage deployments.
