Would like to request to support 2nd (or more?) HDD (or SSD) in order to support larger media libraries and/or analytics data collection.
Also discussed here: External disk for datas and here: Hassio 2nd HDD not available
As more capable HW becomes more readily (and inexpensively) available it would be great if a 2nd (internal or external) disk could be enabled.
I would like this as well to setup an 2nd HDD for FTP storage.
If you don’t have a problem with community add ons
you can use the adapted samba addon called samba nas
