According to the manufacturer's website, this would be the current firmware in January 2022: Firmware 7.16.0-220 (1/10/2022). This is also continuously updated as needed. When using a single drive solution, I would recommend additional backups, because a disc failure in a single drive concept would result in total data loss. Better backup solutions would be possible with dual drive offerings, for example. There are also alternatives in the form of NAS solutions, which can then also be addressed by other devices. I deliberately do not recommend an alternative, because unfortunately people I tried to help on Digitec recently thanked me with reports of abuse.
