Considering the sheer number of NAS-centric operating systems out there, it’s easy to get overwhelmed when building your Network-Attached Storage server. If you’ve got enough RAM and are willing to go through a somewhat steep learning curve, TrueNAS is an incredible distro for your file-sharing, data archival, and backup hub. Meanwhile, Unraid is great for folks who don’t mind spending some extra money on a no-nonsense NAS distro. Depending on your specific needs, you can also choose between EasyNAS, Rockstor, XigmaNAS, and a couple of other cool options.
