It's free as in beer, with commercially supported plans and hardware, it's well supported and the open source version is kept up to date, works on lots of hardware and many plugins/addins. Review collected by and hosted on G2.com.

nothing much can be a bit of learning curve compared to some pre-built commercial system. Review collected by and hosted on G2.com.

You can put the free version on any hardware and runs really well even on the older hardware. Review collected by and hosted on G2.com.

I cannot create storage tiers for hybrid storage. most often we require performance with high capacity without breaking the bank. Review collected by and hosted on G2.com.

I can't really find much bad to say except that it's really great to use, the only thing I would like to see is more backup integration from different providers Review collected by and hosted on G2.com.

I am brand new to hosting my own data solutions but using trueNAS was incredibly intuitive. I now host my own NAS which I intend to use to back up documents, photos and video. At the same time, I can also host game servers as plugins in order to play hosted games with my friends online without paying a monthly subscription fee. I still have a lot to learn, but the documentation has been great so far and there are a lot of users willing to help on forums that I now frequent. Review collected by and hosted on G2.com.

I think what I dislike is mostly attributed to my inexperience with this kind of software. I don't fully understand the capabilities or implications of certain options that are made available, and I am proceeding with caution but also learning along the way. I would love a step by step guide to common end user goals instead of multiple videos about certain features. I think documentation like this would really help cut down on the amount of time it takes users to get a basic trueNAS system online. Review collected by and hosted on G2.com.

Data integrity guaranteed by ZFS can't be touched. Outstanding value of TruNAS appliances vs the competition, which have proved quite reliable. We've received excellent tech support in the 4 years we've deployed them. The flexibility of file and block storage has proved useful. Near SSD performance with inexpensive SATA disks in our use cases saved us a lot of money. As long as the working set is in memory, it is faster than all-flash storage. All-flash systems are less expensive than competing spinning disk offerings from Tier 1 providers. We have more TruNAS systems than any other and had fewer problems than with Pure or EMC systems.

No practical ZFS deduplication yet.

The X series appliances have some annoying quirks. When it comes to redundant power and we've had issues where we had to replace the chassis to correct a false alarm for power redundancy. We never actually lost redundancy, but the chassis reported a PSU failure for one bay no matter what supply was installed. The other issue is that there is no way to power off the system cleanly from the chassis or web UI. If you shut down the system in the GUI the system fails over to the standby controller. This requires a bit of a dance to perform a clean shutdown. Review collected by and hosted on G2.com.

TrueNAS is shockingly easy to use for something that may seem complicated. The official guides plus community guides really helped me set up my NAS in exactly the way it needed to be set up. And this was coming from very little experience in the network storage space. Even a total newcomer who is comfortable with tech can set up TrueNAS and customize it to their needs.

TrueNAS has no downsides in the way that I use it, although there may be some for advanced users. But if it's good enough for Linus Tech Tips, then I think it's probably a good choice for many users. There have been a few things that caught me off guard. For example, they implemented a change that required a user account to connect to the network drive, instead of using the root account. But a quick online search showed me that the community had already discussed it. It was an important detail that I had to find out by running into the issue, but I am glad to see that security is always top-of-mind at TrueNAS. Review collected by and hosted on G2.com.
