By "scan" I assume you mean use OCR to extract text?

The OCR feature on Google Drive is pretty limited.

It will scan images or PDFs upto 2MB in size, which isn't much. A single page of text scanned at moderate resolution and stored as JPG format will sometimes be more than that. Reducing the resolution will allow more than one page, but also make the OCR results less reliable. If you want to store multi-page PDF scans or TIFFs you'll be out of luck.

I tested a single scanned page from an insurance document and it did work, I could (after a few minutes) search on words in the document.

I think you would be better to consider storing the images on Google Drive, after pre-processing with a separate OCR library.
