We mainly use the 'jail' service.

In our company we develop javaEE software with deployment on a Tomcat server, then some nodejs services, relational databases such as Mysql and NoSQL such as Mongo, a GitLab environment like corporate code repository, corporate chat with rocketChat, and a Maven private repository, these are some that come to my mind.

Therefore, all these applications, thanks to 'jails', find an ideal environment where they can be installed and run.

Obviously, the primary purpose of a corporate NAS has also been put to use. The ability to create users and manage permissions with ACL is simple and fast to use.

We are using FreeNAS as a network storage solution, which acts a repository for our data. We have a large amount of data being stored.

I'm just using it at home for my personal use, and I use it primarily for transferring large video files between temporarily storing large video files between computers. I also use it as a backup for my photographs and videos, and things like that, as well as some important documents.

We mainly use FreeNAS for network-attached storage together with other solutions. 

I use it primarily for backup and for transfer of very large files between Windows and Linux computers on my LAN.

We use it for our interim backup solution. We are using the latest version.

Our primary use case of this solution is for storage of our research; for privacy.
