Last week (so yeah, I am late, sue me), Google announced that the storage upgrade of Google One will become available in the US immediately; other countries will still have to wait a week or few.

Google One plans are: US$1.99 for 100 GB, $2.99 for 200 GB and $9.99 for 2 TB of space. Already existing 1 TB plans will be upgraded to 2 TB free of charge. Plans that provide over 2 TB of space will have their prices unchanged. As for Google Drive, it offers the first 15 GB for free. Additional 100 GB cost $1.99, 1 TB costs $9.99 and 10 TB cost $99.99.
