Comparison
Ceph vs SeaweedFS
Overview
Ceph is an open-source, software-defined storage platform that provides object, block and file storage from a single cluster. Highly scalable and self-healing, it is widely used for private clouds and large-scale infrastructure, with an S3-compatible object gateway (RGW).
SeaweedFS is an open-source distributed storage system optimised for billions of small files. It offers an S3-compatible API, a Filer for POSIX-like access, and tiered cloud storage, focusing on fast access and simple operations at scale.
Which should you choose?
Ceph is unified distributed storage — object, block, and file together — massively scalable and self-healing, but operationally heavier, fitting SMB/enterprise. SeaweedFS is simpler and specifically optimized for billions of small files with a POSIX-like filer, scaling to enterprise too but with a lighter footprint. Choose Ceph if you need one system covering object, block, and file storage at exabyte scale; choose SeaweedFS if your workload is small-file-heavy and you want a lighter-weight system.
TLDR
- —If you need one system covering object, block, and file storage at exabyte scale, choose Ceph.
- —If your workload is small-file-heavy and you want a lighter-weight system, choose SeaweedFS.
