FreeNAS suited really well in managing our legacy systems and it handled all our network flows really well, less maintenance is required on our part. FreeNAS also gave the option to switch to TrueNAS for free as now its support is limited. The major issue that we faced was with the installation as it is really complex and required lots of time. Rest all is good and FreeNAS still works well on our systems.
I highly recommend it because it's the most used operating system in the world. If you work with other organizations or share info, it's easier if you have the same system instead of Linux, for example. Also, a large number of employees know how to use it, but not so many know how to use Linux or macOS.
An all-purpose operating system for business or personal users. Overall, the OS is very user-friendly and intuitive, enabling even new users to quickly utilize the system. The same can be said about the apps within Windows. There is also good cross-functionality between applications, although the ease of use could be improved.
Before swapping to FreeNAS, we'd been using plan old Linux servers running Samba and NFS with ZFS storage underneath. This worked really well for our requirements at the time but required a lot of administration when new versions came along, or new users had to be added or drives needed replacing, and so on. FreeNAS did away with 95% of that work and does a much better job too.
We selected Microsoft Windows because of the user friendly nature of it and a big factor is that other user never used macOS or Ubuntu so the productivity will decrease a lot because you have to explain a whole new OS. I always only recommend macOS or Ubuntu if you are a graphic designer of a developer. But for the day to day office work Microsoft Windows is the way to go.
