I recently bought a basic NAS for home use. The NAS is a nice Terramaster F2-425, which is a very basic RAID1-only NAS with a decent CPU and 2.5Gb network. Terramaster allows users to either use its custom Linux-based TOS or install any other operating system supported by the x86_64-based platform. Note that this model does not mount any NVME unit for the OS, as for the F2-424.
