I first wrote about Google One in May 2018, when it was still shrouded in secrecy. The new storage program with improved storage capacities was an invitation-only program until today (for US residents anyway).

Per the original (Google Drive) model, storage is shared across all of the Google properties you use (GMAIL, Photos stored in full resolution, Drive, etc.)

100 GB for $1.99
200 GB for $2.99 (New)
2 TB for $9.99 (2TB for the price of 1TB on the old plan)
10 TB for $99.99
20 TB for $199.99
30 TB for $299.99

If you use the Google Family sharing program (not available to Google Apps accounts, unfortunately), you can share your Google One storage with up to 5 family members. In addition to storage, Google is offering Google Play credit to Google One subscribers and promises to add even more benefits (24x7 support is now also included).

Many still see the Google One page as invitation only but expect this to change shortly. Rolling this new program out to its millions of customers is likely being undertaken in stages.

As a Canadian, I anxiously await any indication about when it will open for us.
