I think SQL Server cube data is stored physically on disk. This is because the cube will hold pre-aggregated data across the specified diemnsions. If the data is physically stored then it will be retrieved fast for reporting purpose.
Answer is... Yes, may be 😀
Let me quote Microsoft documentation about it, nothing is more clear than that... "Storage may include only the cube metadata, or may include all of the source data from the fact table as well as the aggregations defined by dimensions related to the measure group. The amount of data stored depends upon the storage mode selected and the number of aggregations."
Hope this helps.
