Create subsite(s) in OneDrive for Business

[arpitpanchal]

I was looking at creating subsite(s) in the OneDrive for Business. 

I've been successfully able to create subsite(s) in OneDrive for Business,  but I wanted to understand if this is supported approach for OneDrive for Business?

My use case is around using the Enterprise keywords and managed metadata in the OneDrive, however that is not available in OneDrive for Business. However, creating subsite in OneDrive allows both of this capabilities.

Note that SharePoint team site is the option, but that requires additional tenant storage based on the amount of data i'll need to store.

Can someone please help if they have insights/thoughts around this?

Thanks and Kind Regards,

Arpit

Well, even this is a scenario supported I will avoide it since the idea of OneDrive for Business is to be used as personal storage and not for ECM scenarios

Thank you @Juan Carlos González Martín for update.

What if the data stored is function (or use case) oriented data instead users personal data?

Should this be a valid implementation then?
