I confirm this, I used SeaweedFS to serve 1M users daily with 56 million images / ~100TB with 2 servers + HDD only, while Minio can't do this. Seaweedfs performance is much better than Minio's.
The only problem is that SeaweedFS documentation is hard to understand.
Why skipping SeaweedFS? It rank #1 on all benchmarks, and has a lot of features.
