If you are a business and want to use Google Drive, then your only option until now was to buy a full G Suite subscription, even if you don’t want or need access to the rest of the company’s productivity tools. Starting today, though, these businesses, will be able to buy a subscription to a stand-alone version of Google Drive, too.

Google says that a stand-along version of drive has been at the top of the list of requests from prospective customers, so it’s now giving this option to them in the form of this new service (though to be honest, I’m not sure how much demand there really is for this product). Stand-along Google Drive will come with all the usual online storage and sharing features as the G Suite version.
