If you use the cloud for storage, as I do to a certain extent (or even feel that you may need more online storage in the future), the more free space you have the better. Google is currently offering an increase of storage on Google Drive for simply checking your account security settings. By doing so you will go from 15gb to 17gb of free online storage. Sounds great to me and I have taken up the offer. It may provide you with needed extra space in the future for online storage of family history files.
