You no longer have to be a paying Google Drive personal customer to use the expanded One plans. As of today, Google One is available to anyone in the US willing to pay for cloud storage. As before, it's about considerably more than offering more storage for the money. You now have access to a $3 per month 200GB plan and a more accessible $10 per month 2TB plan, but the main allure for many could be family sharing. A total of six people can access the same storage under a single bill. If you'd rather not pay for separate accounts (or just want a shared account), One makes better financial sense.
