Proxmox VE vs Unraid – what are the key differences?

When it comes to managing servers, virtual environments, and storage, the two popular solutions in the market are Proxmox VE and Unraid. Both offer robust features and capabilities, but each has its unique strengths and areas of application. In this article, we will delve deep into both these systems, comparing them in terms of their features, flexibility, ease of use, and cost to help you determine the right solution for your specific needs.


Let’s begin with a brief introduction to both Proxmox VE and Unraid.

Proxmox Virtual Environment (VE): Proxmox VE is an open-source server management platform that offers the ability to manage virtual machines, containers, storage, and network. It combines KVM virtualization and LXC containers in a single, web-based interface. It is especially known for its enterprise-class features and high flexibility.

Unraid: Unraid is an operating system designed to handle Network-Attached Storage (NAS) and to be a hypervisor. The primary strengths of Unraid are ease of use, the ability to add drives of various sizes, data loss protection, and the ability to run Docker and VMs.

Features and Capabilities


Proxmox VE: Proxmox VE supports both KVM for full virtualization and LXC for container-based virtualization. This gives you flexibility in managing your server resources, providing the ability to run a mix of Linux and Windows applications.

Unraid: Unraid provides a KVM hypervisor as well, allowing you to run a number of VMs, but it does not offer container-based virtualization like Proxmox. It does, however, support Docker for application containerization, which can meet the needs of many users.

Proxmox VE: Proxmox offers a range of storage options. It supports ZFS, Ceph, NFS, GlusterFS, and others. It also has advanced features like storage replication, high-availability, and snapshots. However, it does not allow adding storage space on-the-fly as easily as Unraid does.

Unraid: Unraid takes a more straightforward approach to storage management. It uses its proprietary software to create a storage array that can have drives added or replaced one at a time. Its key strength is the ability to mix and match drives of different sizes.

Ease of Use

Proxmox VE: Proxmox provides a web-based management interface, making it easy to manage VMs, containers, and storage. However, it may have a steeper learning curve for beginners compared to Unraid due to its more complex, enterprise-oriented features.

Unraid: Unraid is often lauded for its simplicity and user-friendly web interface. Setting up and managing your system is generally easier with Unraid, making it a good choice for beginners or those who want a less hands-on experience.


Proxmox VE: Proxmox VE is an open-source solution and can be used free of charge. However, if you require professional support or access to the stable enterprise repository, subscription plans are available.

Unraid: Unraid is a commercial product with a license fee. The cost varies depending on the maximum number of storage devices you plan to use.


Both Proxmox VE and Unraid offer compelling features, but they cater to slightly different user needs. Proxmox VE is a powerful, enterprise-level solution that offers high flexibility and broad feature-set for managing virtual environments. It’s an excellent choice for businesses and advanced users who need comprehensive virtualization and storage features.

On the other hand, Unraid shines with its simplicity and unique approach to storage. It’s particularly useful for home users or small businesses looking for a user-friendly solution to run VMs, Docker apps, and handle their NAS needs. In the end, your choice between Proxmox VE and Unraid will depend on your specific requirements, technical expertise, and budget.
