FreeNAS is an operating system based on FreeBSD and aimed at use in NAS (Network Attached Storage, or network connected storage), and basically we can say that it allows us to take advantage of the storage devices as external drives, for access them from any other device connected to the same network: a laptop or desktop computer, a smartphone, tablet, Smart TV, etc. Much of its success is due to the fact that it is very simple to install, and also because it actually takes up very little disk space.
In the last hours FreeNAS 9.3 arrived, with a few major improvements such as its new and reorganized web interface, already with fewer tabs than before (one of the features that its users criticized the most) and its new installation wizard (setup wizard), which now offers a lot of help to those who install this tool for the first time since it allows them to configure absolutely all the aspects from there.
In addition, the ISO image can now be used both to boot from a CD and from a USB stick, and many options were added for the boot process. On the other hand, now the boot devices can be partitioned with the ZFS file system, with support for mirroring one or more of them, and the package update process is now much faster than before thanks to the implementation of a system that allows the download of the modifications that they receive instead of downloading them completely again (although this can also be done if preferred). Regarding this, in addition, now you can opt for a more stable installation, with fewer updates, or for a more aggressive one where all the changes are available almost immediately.
Regarding the most operational options we can mention the support for NFSv4 (includes kerberos), Samba 4.1.13 and for share files using WebDAV, and in security matters we can mention the vcryptographic validation of all updates, in addition to the management of passwords, which are now encrypted in the FreeNAS database.
