The world’s number one open-source operating system, TrueNAS brings the performance and features of the legendary OpenZFS file system in an easy to use package. Available in two free and open-source software versions, TrueNAS also comes as a professionally-supported Enterprise solution when coupled with iXsystems branded hardware.
It's tempting to treat file, block, and object storage as three competing options and just pick one. SNIA, the vendor neutral group that defines these categories, describes block storage as data handled in fixed size chunks, file storage as a stream of bytes...
TL;DR TrueNAS 27 is the next major release of TrueNAS, built on OpenZFS 2.4 and Linux kernel 6.18. It was previously numbered TrueNAS 26. RC.1 is the first release candidate, and TrueNAS 27.0 is scheduled for early December 2026. Highlights: TrueSearch and WebShare:...
How a few bytes of difference means your data might be locked to hardware or a vendor you can't easily replace. You chose a ZFS-based NAS for the right reasons. ZFS has a decades-long track record of data integrity, mature tooling, and a thriving open-source community...
The S3FS Translation Tax If you’re setting up OME-Zarr for high-throughput microscopy, you probably assume you need to use S3 for the entire pipeline. That’s a mistake that will bottleneck your local ingest. OME-Zarr is an encapsulation format and programming library...
If your cloud storage bill doesn't match what it used to, and you're already evaluating what it takes to move your data back on-premise, you're part of a measurable industry shift, not trying out an isolated experiment. Enterprises have already repatriated over 20% of...
TrueNAS is the first storage platform certified under the newest Veeam Ready Appliance category: All-In-One (virtualized). It's built for servers that run the Veeam Software Appliance (VSA) directly, instead of just sitting behind it as a repository target. As of...
You click the button. TrueNAS builds the disks. Proxmox VE has become one of the default landing spots for teams leaving VMware, and TrueNAS is already a common storage layer underneath those clusters. Most of those deployments run today on NFS or hand-cut iSCSI LUNs,...
TLC (Triple-Level Cell) and QLC (Quad-Level Cell) are the two NAND flash types behind most enterprise SSDs today. TLC stores 3 bits per cell, QLC stores 4. The extra bit gives QLC roughly a third more density per wafer, and typically twice the density per SSD, at the...
Run a TrueNAS pool long enough, and someone will warn you: stay under 80% full. The "80% rule" for capacity is like a ghost story of ZFS storage administration. Everyone has heard of it, but ask a room of admins why it exists, and the answers get vague fast. It gets...
Patch notes are supposed to be boring. A short list of CVEs, a version bump, nothing to see here. That stopped being true the moment AI models got better at finding vulnerabilities than most people are at writing proof-of-concepts for them. TL;DR: TrueNAS 25.10.5...
