ZFS vs Btrfs: Architecture, Features, and Stability #2
ZFS and Btrfs both aim to modernize storage by combining filesystems and volume management, but they were built with very different priorities. This article examines their architectures, core features, and long-term stability to explain why ZFS remains the preferred choice for data integrity at scale, whereas Btrfs trades reliability for flexibility.
Modern VDI on Proxmox: ZFS Reliability and GPU Acceleration at Lower Cost
Running VDI doesn’t have to mean high licensing costs or fragile stacks. Join this session to see how Proxmox, ZFS, and GPU acceleration work together to deliver reliable, high-performance virtual desktops without lock-in.
ZFS in Production: Real-World Deployment Patterns and Pitfalls
ZFS is widely trusted for large-scale storage, but production environments expose design mistakes, operational drift, and false assumptions that don’t appear in smaller deployments. This article explores real-world ZFS deployment patterns, common pitfalls, and the operational practices required to keep ZFS reliable at scale.
Klara’s Expert Perspective on OpenZFS in 2026 and What to Expect Next
How will OpenZFS evolve in 2026? Klara’s experts outline their predictions across hardware, system design, and reliability. Read on for a grounded look at what to expect.
Understanding ZFS Scrubs and Data Integrity
ZFS scrubs verify the integrity of all allocated data and metadata blocks in a storage pool by validating checksums and repairing corruption through redundancy. This article explains how ZFS scrubs work, how they differ from resilvers and traditional filesystem checks, how to interpret zpool status output, and why regular scrubbing is critical for preventing silent data corruption in production storage environments.
Unwrapping ZFS: Gifts from the Open Source Community
OpenZFS users got a stack of new “gifts” in 2025: better allocation, stronger hybrid-pool performance, faster encryption, and long-requested rewrite tools. Here’s what the community delivered and the benefits you can unwrap right now.

Can You Have Too Many VDEVs? A Practical Guide to ZFS Scaling
ZFS is built to scale. With the right VDEV layout, adding VDEVs delivers more IOPS, quicker rebuilds, and consistent behavior as your pool grows.
Is DWPD Still a Useful SSD Spec?
DWPD (Drive Writes Per Day) is an SSD endurance metric that estimates how many times a drive’s full capacity can be written each day over its warranty period. This article explains how DWPD is calculated, why vendor ratings can be misleading, how NAND flash wear actually works, and which factors — including bit density, overprovisioning, and usable capacity — better predict real-world SSD lifespan and performance.
How to Set Up a Highly Available ZFS Pool Using Mirroring and iSCSI
Turn commodity hardware into a fault-tolerant SAN. This ZFS pool setup with iSCSI shows how to combine mirrored storage and FreeBSD jails for high availability without vendor lock-in.
