TrueNAS SCALE incorporates all the major TrueNAS CORE storage and sharing features with a web interface based on Debian GNU/Linux. Because SCALE shares the same UI as the FreeBSD-based TrueNAS CORE, users will notice there are similarities. However, SCALE does incorporate some differences, primarily in component naming.


TrueNAS Core utilizes a numerical listing of drives in a system.


TrueNAS SCALE uses a lettered format for drive identification.


SCALE still labels NVMe drives with a numeric value.


TrueNAS CORE utilizes driver information and enumeration to assign an interface name.


TrueNAS SCALE uses PCI location to assign an interface name.
