MinIO has standardized on-prem S3 with a single binary, Ceph still dominates enterprise on-prem with RGW + RBD + CephFS, and SeaweedFS / Garage offer lighter alternatives. On Kubernetes, OpenEBS Mayastor, Longhorn, and Rook compete via CSI. In the cloud, Cloudflare R2, Backblaze B2, Wasabi, and Storj DCS started an egress war, while AWS S3 cemented the "S3 is the new disk" thesis with Express One Zone and S3 Tables (Iceberg). This guide covers MinIO, SeaweedFS, Ceph, Garage, JuiceFS, OpenEBS, Longhorn, Rook, Portworx, R2, B2, Wasabi, Storj, S3 Express, S3 Tables, and the local filesystems beneath them — ZFS, btrfs, XFS, bcachefs.

MinIO가 단일 바이너리로 온프레미스 S3를 표준화하고, Ceph이 RGW·RBD·CephFS 삼각 편대로 여전히 엔터프라이즈를 지키며, SeaweedFS·Garage가 가벼운 대안을 제시한다. K8s 위에서는 OpenEBS Mayastor와 Longhorn과 Rook이 CSI로 경쟁하고, 클라우드에서는 Cloudflare R2·Backblaze B2·Wasabi·Storj DCS가 egress 전쟁을 시작했고, AWS S3는 Express One Zone과 S3 Tables(Iceberg)로 "S3가 새로운 디스크다" 명제를 굳혔다. 이 글은 MinIO·SeaweedFS·Ceph·Garage·JuiceFS부터 OpenEBS·Longhorn·Rook·Portworx, R2·B2·Wasabi·Storj, S3 Express·S3 Tables, ZFS·btrfs·XFS·bcachefs까지 2026년의 전체 분산 스토리지 스택을 정리한다.
