Ceph is more production-ready, and has a lot of things SeaweedFS I believe doesn't yet have (such as consistency checking and rebuilding of failed nodes). It also has FS layer capability. SeaweedFS can use a filer but it currently doesn't support indexing (so you can't do subdirectory lookups for example, you would need to know the full filename). SeaweedFS is fundamentally trying to do a different thing than Ceph is, and it benefits certain use cases. Reading the Facebook Haystack paper will give you an idea of the differences. That said, I'm extremely impressed with how simple the interface is. It's very easy to get started.
