TrueNAS

Pros: TrueNAS is truly a great platform that has humble beginnings and is poised to be a leader in the storage marketplace.

Cons: There is nothing to dislike. Your data is your data, when and where you want it; setup there is little to no chance you will experience any data loss. I wish there was a mini version that was based on only nvme storage like consumer grade Sabrent pocket SSDs. Would like to see a unit that can accommodate like all M.2 2280 and have the footprint that represents these 1" x 3" SSDs;

Overall: So many false flags and hopes are introduced into the marketplace hoping they will be the next "big idea" product or service; TrueNAS seems to have accomplished this goal. Their product lineup is mature and robust.

Pros: -Easy to setup for a non-IT person
-Lots of community support
-Great performance
-Free for us home users

Cons: -Some information available contradicts others (some testing needed)

Overall: Would 100% recommend to others! First time setting this up for home use with no issues. Getting great read/write performance.

Pros: Excellent product, works perfectly for my business NAS. Easy to use, robust, easy to setup network shared folders.

Cons: Legacy NVIDIA drivers not supported, could be useful for old graphic cards.

Overall: I really liked TrueNAS scale OS in general. Excellent product, works perfectly for my business NAS. Easy to use, robust, easy to setup network shared folders.

Pros: Better usability on my opinion than on commercial NAS (QNAP)
DIY possible on own hardware and it was quite easy to setup.

Cons: Access control a bit confusing and also NFS / Samba related configurations.

Modifying existing Storages is very tricky (extending size etc).

Overall: Generally well performing and easy NAS system to setup and use.
Also underlying ZFS is working quite well.

Pros: Customization is key, TrueNAS offers almost everything with this feature.

Great use cases such as plex and vm running on top of the system.
The UI is awesome.

Cons: Jail system sometimes is hard to handle but overall good experience.

Overall: Excellent product with great features, the hardware is pricy, I'll continue recommending it to everyone.

Pros: Expandable to other technologies like Kubernetes / Docker. Without overwhelming the user of in depth cluster configs.

Cons: Especially on older hardware I found issues with the recent major release. Mostly regarding GPU passthrough.

Overall: Trusty always on NAS that hosts all solutions that are needed in a home scenario. Enterprise was unfortunately not in my scope since my use case differs a little there.

Pros: The installation process on the right hardware is smooth, in older PC it might be a little more difficult but overall great, the service is nice.

Cons: It's closeness, it's difficult to install certain things.

Overall: Great, it was a really pleasant experience and very informative, also really great to know how to start a server.

Lots of features.
Open source. Good support. Good access management with ACL.

Cons: Issues after updates.
Long startup time.
Web GUI is sometimes unresponsive and slow.

Overall: Overall a very capable and handy OS. Has lots of features and is quite stable. Only the web GUI is sometimes a bit slow.

Pros: TrueNAS offers robust data storage solutions with advanced features, scalability, and excellent data protection. Impressive performance & reliability.

Cons: TrueNAS can be complex to set up and configure, requiring technical expertise. Limited integration with certain third-party applications and potential scalability challenges for extremely large-scale deployments.

Overall: Overall, TrueNAS provides powerful data storage capabilities with advanced features, strong performance, and reliable data protection. While it may require technical knowledge for setup and has some limitations in integration and scalability, its pros outweigh the cons, making it a solid choice for businesses and organizations in need of robust storage solutions."

Pros: Great solution for self hosted storage.
Set up is easy, even using proxmox.
Easy way to set up as "time machine" volume.

Cons: The web ui is not a 100% intuitive.
Setting up data sets is not a 100% clear to me.
