The short version

  • Only Rook has a free tier, so it costs nothing to try first.
  • Each has a real cost: Portworx bare metal nodes are charged at 1.11 USD per node hour against 0.33 for virtual nodes, so a bare metal cluster costs more than three times a virtualised one for identical capability.; Rook rook automates Ceph but does not abstract it, so an incident still demands Ceph expertise, and organisations without it end up hiring consultants at exactly the wrong moment.
  • They diverge on capability: Portworx covers Container-native volumes, Rook covers Ceph operator.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Portworx

  • Running a production PostgreSQL or Cassandra cluster on Kubernetes and needing the data to survive node lossnot Rook
  • A platform team offering self-service databases to developers on an internal Kubernetes platformnot Rook
  • Failing over stateful applications between clusters in different regions as a disaster recovery positionnot Rook
  • An OpenShift estate where the built-in storage option does not meet the availability requirement for stateful setsnot Rook

Rook

  • An on-premises Kubernetes platform needing block, shared filesystem and S3 storage without buying three productsnot Portworx
  • A team that already runs Ceph and wants its lifecycle managed declaratively inside Kubernetesnot Portworx
  • A large cluster where three-way replication overhead is unaffordable and erasure coding is requirednot Portworx
  • An organisation building a private cloud that cannot use managed cloud storage services for residency reasonsnot Portworx

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Portworx

  • Bare metal nodes are charged at 1.11 USD per node hour against 0.33 for virtual nodes, so a bare metal cluster costs more than three times a virtualised one for identical capability.
  • A 1,000 node hour monthly minimum applies, which means small or intermittent clusters pay for capacity they do not consume.
  • Replicating volumes across nodes consumes real capacity and network bandwidth, so the underlying infrastructure cost rises alongside the licence in a way the node hour rate does not show.
  • Pure Storage ownership means roadmap priorities are set by an array vendor, and buyers should confirm that hardware independence remains contractual rather than assumed.
  • Operating it well requires Kubernetes storage expertise, and teams that adopted Kubernetes to simplify operations often find they have added a distributed storage system to run.

Rook

  • Rook automates Ceph but does not abstract it, so an incident still demands Ceph expertise, and organisations without it end up hiring consultants at exactly the wrong moment.
  • There is no vendor and no SLA; the realistic commercial support routes are IBM Red Hat OpenShift Data Foundation or an independent Ceph consultancy, both of which change the cost picture entirely.
  • Ceph is resource hungry, needing substantial memory and dedicated disks per OSD, so the hardware cost of a properly sized cluster is often underestimated.
  • Recovery and rebalancing after a disk or node failure generates heavy background input and output that can degrade application performance for hours, which surprises teams sizing for steady state.
  • Minimum viable clusters require several nodes with several disks each, so it is impractical at small scale and the entry hardware cost exceeds simpler alternatives.

Questions people ask

Is Portworx or Rook better?
Neither clearly leads. Portworx starts at $0.33/node hour and Rook at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Portworx or Rook?
Rook has a free tier; the other does not. Paid plans start at $0.33/node hour for Portworx and Free for Rook.
Does Portworx or Rook run on more platforms?
Portworx runs on Linux. Rook runs on Linux, Kubernetes.
Can I use Rook for free?
Yes. Rook has a free tier, so you can try it without paying. Portworx starts at $0.33/node hour.
What is Portworx best used for?
Portworx is most often used for running a production postgresql or cassandra cluster on kubernetes and needing the data to survive node loss, a platform team offering self-service databases to developers on an internal kubernetes platform, failing over stateful applications between clusters in different regions as a disaster recovery position, an openshift estate where the built-in storage option does not meet the availability requirement for stateful sets. Of those, running a production postgresql or cassandra cluster on kubernetes and needing the data to survive node loss and a platform team offering self-service databases to developers on an internal kubernetes platform are not what Rook is typically brought in for.
What can Portworx do that Rook cannot?
Portworx covers Container-native volumes, Failure domain placement, Volume encryption, Database automation. Rook covers Ceph operator, Block, file and object, Erasure coding, CSI driver.

Answered from the vendors’ own pages

Portworx: Is Portworx tied to Pure Storage hardware?

No. It runs on any Kubernetes distribution over any underlying storage, though Pure has owned it since 2020 and sets the roadmap.

Rook: Who supports it in production?

Nobody by default. IBM sells Red Hat OpenShift Data Foundation, which is supported Rook and Ceph, and independent consultancies sell Ceph support. Decide this before deployment.

Portworx: What does a real cluster cost?

At 0.33 USD per virtual node hour, twenty nodes running continuously is roughly 4,800 USD a month. Bare metal at 1.11 USD per node hour is around 16,000 USD for the same node count.

Rook: Does it need Ceph knowledge?

Yes. Rook handles deployment and routine operations, but troubleshooting a degraded cluster is a Ceph skill and there is no way around it.

Portworx: Is backup included?

No. Portworx Backup is a separately priced product covering Kubernetes application backup.

Rook: Can it replace an object storage appliance?

Functionally yes, through the RADOS gateway, but you take on the operations that an appliance vendor would otherwise carry.
