"huge volume of data" or "huge volumes of data" [closed]

It depends whether you are speaking generally or specifically.

If you are speaking in a general way, then in the same way that we say 'we handle huge cats', with cats in the plural, you would say "we handle huge volumes of data".

If you are speaking specifically, about one project for example, the in the same way that you would say 'we handled a huge cat' you would say "we handled a huge volume of data".

"Huge volume" implies that there is simply a lot of data. A huge, torrential deluge of data. Data, data, everywhere. But not compartmentalized, necessarily - just a lot of it.

"Huge volumes", though, implies that there are several volumes - sets, categories, groupings - that each contains a huge amount of data.
