Civo Block Storage

Civo Block Storage is managed NVMe storage for Civo compute and Kubernetes. It is a strong fit for teams keeping databases or application data on Civo, but the 1 TB volume limit and lack of multi-attach narrow its reach.

Overview

Volumes provide persistent capacity for databases, application back ends, and other compute workloads. In Kubernetes, Civo’s CSI driver provisions storage through a PersistentVolumeClaim. Volumes can also be grown, detached, and attached to another instance in seconds, which is useful when capacity or instance placement changes. On Linux, administrators still need to partition, format, mount, and resize volumes using operating-system tools.

The service uses NVMe drives across a 25GbE network and is positioned for sustained workloads such as AI training, analytics, and production databases. Civo states a 99.95% uptime SLA for each volume, with redundancy built into the architecture and two additional data mirrors across distributed nodes. Unlimited data transfer, no egress fees, and no per-IOP charges make costs less sensitive to moving data or storage activity.

Key features

• Kubernetes provisioning: CSI and PersistentVolumeClaim support provide a direct way to request persistent storage for workloads in Civo Kubernetes clusters.
• Resize and reattach: Growing a volume or moving it between instances in seconds is practical for changing capacity needs and instance maintenance. The 1 TB maximum remains a firm ceiling.
• Automation and snapshots: Dashboard operations are also available through the API and CLI. Civo cites Terraform provisioning and CI pipeline snapshots as automation examples; snapshots are supported.
• Transfer terms: Unlimited transfer without egress or per-IOP charges removes two common sources of variable storage cost.
• Security credentials: The product page displays AICPA SOC 2, Cyber Essentials Plus, ISO 27001, Crown Commercial Service, and UK Government G-Cloud badges.

Pricing

Civo presents two volume plans, and its pricing model is marked freemium even though there is no free plan.

• Volumes — free: Usage is calculated hourly and billed monthly, per GB. The plan describes persistent volumes with two additional data mirrors across distributed nodes. It suits variable or modest capacity needs, but the zero monthly figure is not a free allowance: usage is billed.
• Block storage — $10.86 a month: Billed at $10.86/month per 1TB, this includes 1TB of NVMe block storage, unlimited data transfer, no egress fees, and no per-IOP charges. It suits workloads that need a full terabyte and value predictable transfer costs. The cap is 1 TB per volume.

The pricing summary also says paid plans start at $5.43/mo, while the named Block storage plan is priced at $10.86 a month for 1TB. Confirm which starting price applies to the intended capacity before budgeting. There is no free plan, and no trial, renewal term, or seat allowance is stated.

Platforms

Civo lists API, Linux, macOS, web, and Windows platforms. The documented Linux setup involves partitioning, formatting, mounting, and resizing with tools such as parted, mkfs, and resize2fs, so this is managed storage rather than a substitute for operating-system volume administration.

Who it's for

Choose Civo Block Storage when persistent NVMe capacity for Civo compute or Kubernetes matters, especially for databases and application back ends that benefit from snapshots, automation, and transfer costs without egress or per-IOP fees. It is less suitable for designs needing volumes larger than 1 TB or simultaneous multi-attach.

Pros and cons

• Pro: CSI provisioning, API and CLI access, and Terraform and CI snapshot examples support automated infrastructure workflows.
• Pro: Two additional mirrors, a stated 99.95% uptime SLA, and unlimited transfer without egress or per-IOP fees address resilience and cost concerns.
• Con: A 1 TB maximum volume size limits larger datasets or single-volume growth.
• Con: Multi-attach is not supported, ruling out workloads that require one volume attached to multiple instances at once.
• Con: The Linux setup still requires manual partitioning and filesystem work, despite the managed deployment model.

Alternatives

For broader infrastructure choices, browse Container Orchestration Software.

Choose Kubermatic Kubernetes Platform instead if you need an open-source Kubernetes platform with a free Community Edition under Apache License 2.0; Enterprise Edition uses custom pricing.

MicroK8s is worth considering for free Kubernetes on Linux, macOS, or Windows, with no license fees and an Ubuntu Pro Personal option covering up to five machines.

Pick .NET instead when you need its free software plan for up to 1,000 nodes rather than Civo-managed block volumes.

Google Kubernetes Engine is an alternative for managed Kubernetes with a free tier that applies $74.40 in monthly credits per billing account to zonal and Autopilot clusters.

Kubernetes is the free, open-source platform option for teams seeking orchestration software rather than managed Civo block storage.

Consider Docker Swarm if you want orchestration built into Docker Engine without additional orchestration software.

KubeSphere is another open-source Kubernetes container platform option.

Rancher offers a free open-source platform with community support, with Rancher Prime available under custom pricing.

Verdict

Civo Block Storage is a sensible choice for teams running Civo compute or Kubernetes workloads that need persistent NVMe volumes, snapshots, and transfer costs without egress or per-IOP fees. Its stated redundancy and quick resize or reattach options strengthen the case. Look elsewhere if a workload needs a volume above 1 TB or multi-attach, and verify the applicable starting price before committing.
