I also have nothing bad to say about TrueNAS CORE. As a community-driven, FOSS, ZFS supporting storage and backup solution (though RAID is not a backup), iXsystems has done a great job in educating me in the ways of NAS/SAN solutions and boy do I appreciate them for it! TrueNAS is great tool for redundancy for when I accidentally mess something up in the development environment, I have a system I can rely on to restore my mismanaged files. It has actually helped me while getting hacked as I took it offline to prevent any further damage to my data. My scope is fairly limited, as I am expanding my network for future scalability. I am directly addressing the business problem of needing a backup solution (though NAS/SAN are not necessarily backup solutions) while expanding my storage capabilities. The proprietary setup used by Unraid was also another barrier to my entry, as I prefered to support, the newly established TrueNAS philosophy of FOSS.

It helped me in using an old server at work to make a new datastore and NFS archive. I was able to move everything to it as we replaced our old synology server. This made it so that our users didn't even realize I was doing this in the middle of the day. This also saved our company alot of money on overtime.

It was easy to use, the software is free. You can set it up on many different types of hardware. It does not use / require an actual raid cared. the ZFS file system is amazing and fast / pact with features. You can run VM's on this software provided you have the RAM / Storage. It runs plugins that behave like docker apps like GUAC. One of the most important features for me was the availability of a DARK MODE. Your eyes will thank you so much.

The networking setup if not using DHCP was a bit finicky but not difficult. You have to wrap your head around the fact that it does not use a RAID card. Do NOT use RAID for this software. The software manages all of that directly. Make sure you have a good UPS and you'll be golden.

I didn't like it. While it had all the features I needed I ran into many many hardware compatibility issues. Such as network cards not being detected.

Bad hardware compatibility and I need 40 characters.

TrueNAS has bringed its experience to the storage technology. We used it on the past has a simple NAS system. But today we are planning on our project to use it as a SAN for all our servers.The flip-over was done because it's simplicity on management, the easyness to configure high availability, and the support excellence that is provided to us.We consider TrueNAS has a an indispensable partner for our daily business.

- High Availability - Storage Management - Access Policy Management - Detailed Statistics of the Managed Storage

- Integration with Hyper-V (if it already exists, I didn't found it) - A WHMCs module to connect with the API - File Change Backup (like do a backup of every file change)

I wouldn't hesitate to recommend TrueNAS to anyone.

Dashboard is great, and the layout is better than some of their competitors.

The HA implementation isn't as user-friendly. Before really hashing everything out and learning the qwerks, I had a lot of issues with a two-node pair losing sync. I think this has been fixed in the latest releases, though.

TrueNAS is great for a home user whether experienced or not, due to its ease of use and value.

TrueNAS provides a cost-effective alternative to subscription services like Apple iCloud, Google Drive, etc.

Little bit of a learning curve as some settings and features are not intuitive or new user friendly.

The overall experience has been great. After the initial os config and pod configuration, the system runs very reliably.

What I liked most about TrueNAS scale was the ability to have a ZFS storage management solution and Hypervisor in one product. This made it an easy decision when choosing a server os for my homelab.

The lack of a GUI solution to k8 pod information. I also do not like that when saving a k8 config or updating the pod, will auto start if offline.

While I'm accustomed to using the terminal, I welcome the in-browser graphical UI which anyone can use. Remote administration has never been easier for me and my colleagues, with even those unfamiliar with Linux being able to pick up on things very quickly due to the intuitive design. We deploy NAS and server solutions for clients which can be remotely accessed by us for easy maintenance and administration.

TrueNAS Scale is not as mature as TrueNAS Core, but I have experienced no stability issues thus far.

TrueNAS Scale allowed me to consolidate my whole homelab environment into one single, high performing machine that is robust and scalable to my needs.

I love how easy it is to manage everything in one place. I love being able to run containers and VMs on the same system and assign their data and permissions easily.

While the documentation and guides are great and extensive, it still has a high learning curve that can be difficult for new users to get into. There are some hypervisor functionally currently missing that might get added in the future.

Very happy with my TrueNAS setup. The only down time has been a major powercut!Day to day the system is "invisible" - it just works and I feel confident my data is safe.

Open source software that is designed to do the job whilst making it easy to install and maintain. Prior to installing this software I had no experience of setting up a NAS system. The extra ability to run VMs with in it makes it ever better.

Very little to dislike. TrueNAS core is based on FreeBSD, which is a little different to the Linux which I am very comfortable with but in day to day use it makes no difference.

In the past 8 years I have deployed dozens of systems running FreeNAS and TrueNAS core. With the use of periodic SMART test schedules, ZFS scrubs, built in alerting, TrueCommand monitoring, and a whole host of maturity in the ZFS filesystem itself, I have never lost data because of a flaw in the product. It does exactly what it is designed to do, stops you from making poor decisions and keeps your data safe and uncorrupted.

I have used TrueNAS to solve a host of issues. We use TrueNAS as an iSCSI target for workloads such as video surveillance and VDI. For this workload we have been able to bring new life to existing hardware we already own in order to extend it's useful life longer than we otherwise would be able to. TrueNAS, both CORE and SCALE, have a wide breadth of hardware support. This is something becoming decreasingly common, with major hypervisor players end-of-lifing hardware long before it's useful life has ended. We also use TrueNAS for it's filesharing capabilities. With immutable snapshots and replication, we are able to have warm backups on multiple hardware nodes for important datasets. This is an very easily implemented layer in our backup and DR policies. TrueNAS leverages ZFS which is a COW file system, making snapshots simple and TrueNAS layers on an easy to expose Volume Shadow Copy feature in Windows.

ZFS's implementation of deduplication leaves alot to be desired. TrueNAS CORE and SCALE do not natively support Fibre Channel. TrueNAS SCALE's UI for managing VMs needs maturity and improvement. TrueNAS SCALE's hypervisor needs clustering, HA and "DRS" like feature sets to be competitive at "scale".

I've implemented both for my university and have deployed 5 systems over the past 5 years. Initially replaced two Isilon NAS units with TrueNAS Core systems. Our first ixSystems' hardware replaced an EMC SAN in a remote campus using iSCSI with ESXi as primary storage. Since then we've deployed M40's running TrueNAS for primary and archival storage with Veeam. The only time we've had to touch them has been to upgrade the OS.

TrueNAS is the most popular storage OS for a reason. It is a mature and stable platform that implements Open ZFS on FreeBSD. ZFS is the most reliable file system in existence. It was designed to ensure data integrity and scale to a Zettabyte of storage back in 2001. Most of the features that are taken for granted in a modern storage system were lifted from ZFS. TrueNAS is pretty much set and forget. It's self maintaining and self repairing. It's dynamic caching algorithms can provide flash performance with inexpensive spinning disk. TrueNAS Core runs on the same code base as TrueNAS Enterprise. Core is community supported and can run on any x86 system that meets the hardware requirements, while Enterprise is only available with ixSystems hardware, supports HA and and you can get enterprise support from ixSystems.

HA and enterprise support is only available on ixSystems' hardware.

My overall experience with [SENSITIVE CONTENT] has been rock solid and I’ve been looking forward to trying it out even more powerful hardware to further explore its potential

The fact that TRUENAS uses ZFS as a base filesytems means that it includes a lot of great features out of the box

Being based on BSD means a lot of great things but unfortunately two major downsides: 1: the ecosystem is somewhat than for example Linux, meaning That there may not always be a convenient way to install the application you need BSD is also stingy when it comes to hardware comptibility, meaning that you might have to do some research if you want to make sure your hardware is supported

Basically fulfills all its core goals pretty well, can be had for free for own deployments or can be a paid solution for supported enterprise/business customers.

ZFS has been implemeted great - its stable and performant in the BSD variant (Core), but it has issues in its linux based variant (Scale) due to how ZFS dataset is used as storage filesystem for Docker/Kubernetes functionalities. It's also rather resource prudent.

It is BSD-based in the Core guise, so any BSD issues or support apply here as well. In its linux-based variant (Scale), the ZFS datatset for applications results in thousands of snapshots reported in the UI, due to each layer of each container in use, plus a history of those for rollbacking purposes is saved and shown without any useful filtering option in the snapshots pane/page of the UI and by extension in the CLI. By default, SMB/NFS shares do not expose snapshots of the filesystem in the shares for ease of data recovery upon accidental deletes etc.

Free to use, endless opportunities, great development.

Setting it up requires a certain amount of experience and time.

TrueNAS Core was extremely easy for us to integrate into our company, we managed to get our limited truenas servers up and running within a single day, and within a couple of weeks we were backing up our customers crucial data. A few things that made this process really easy for us was the supported file sharing protocols such as NFS and SFTP which gives us ease of access from our clients servers, and gives our clients easy access to their backups, additionally the built in rsync server made it very easy for us to automate backups for all of our clients in a very short timeframe.

For us, the main drawback of TrueNAS is that it is lacking a built in software firewall, in our client infrastructure's, which are mostly based on cloud providers such as OVH, private networking isn't always available which can make TrueNAS insecure and therefor in these environments we're unable to use it.

A solid system to provide disk storage to my hypervisors.

Super easy to setup, and free if you do not want or need support.

I don't see the need to provide virtualisation on the storage system, but am happy the flexibility provides it for home users

Perfect for sharing mission critical data between users. Easy to backup the data. Uses ZFS = reliability Huge community to help setup and troubleshoot

None so far! We are using trueNAS for over 2 years without any problems / downtime.

We have been using a SAN/NAS since the early 2000's, and had been a Left Hand Networks fan, until they were bought out by HPE. The quality of HPE software declined in subsequent versions, until HPE removed all LHN technology from their products completely. TrueNAS Core is going back to the roots of how a SAN/NAS is supposed to be managed. We will never go back to HPE's bloated, over processed, non-private offerings, thanks to TrueNAS.

Learning how to navigate the menu selections took considerably less time than competing companies (HPE specifically).

The more difficult issue we have come across is losing the IP address of the iSCSI connection on cold restart (power loss from storms), otherwise it's been a solid product.

A pleasure to use, dead-easy to install and setup and pretty reliable

I love the design and layout of the dash.

Occasional lock-ups of installed apps causing the HDD to become slow.

I used FreeNAS from 2010 to 2022 in my home lab. I've run a test lab at a former employer from 2015-2017. In 2022 with the release of TrueNAS Scale, I switched to gain the benefits of beter virtualization, and the ability to run containers.

You can use it as a simple NAS with ZFS for data integrity, ir you can use it for virtualization and containerization (Scale). Especially useful in small or home offices, and indispensable for the IT admin at home.

Older versions were daunting, as the GUI wasn't intuitive. However, TrueNAS Core/Scale received a new GUI in 2022. Creating ZFS storage arrays, building virtual machines, and spinning up containers are a snap!

TrueNAS CORE's wide hardware compatibility make it relatively simple to build a system much more powerful than the NAS appliances from Synology or QNAP by reusing parts laying around in the parts box.

ZFS file system cannot grow a volume like Synology's Btrfs can, by simply adding a drive. This requires more planning.

Extremely feature rich out of the box, it's extremely stable, builds on top of the very stable ZFS & FreeBSD foundations.

Some weird quirks in the web UI, for example the terminal doesn't use the whole screen and can't be resized. Nothing deal breaking as I mostly just SSH into the server.

We use TrueNAS to maximize the value of our existing datacenter hardware into new storage solutions. While there is a still a place for Nimble and 3Par, TrueNAS gives us the flexibility we need to create data pools from our un used physical inventory for staging, deployment, backup, or other various activities with the datacenter.

ZFS, is a core technology that I use to build flexible arrays. When we tested drive failures we found that we needed to plan for additional time in when resilvering the array. We found TrueNAS performance in this area to meet the standards we expect. For the uninitiated this could be undesirable.

Love how easy it is to setup, it's scalability, and the fact that you can build any system yourself, doesn't have to be a branded Server, can just be a white box with some CPU/RAM/Disks if you want.

Easy to setup/deploy. ZFS is a superior file system. SMB works great with Windows and integrates the snapshots with shadowcopies easily. Can even virtualize VM's on TrueNAS (provided you have enough CPU/RAM). Scalable!

There is nothing I like least about TrueNAS
