Today, Google Drive finally made its debut, offering what has become the industry-standard 5GB of free space. Its purchase model is similar to Apple's, Amazon's, and other leaders in this field. We posted earlier about its introduction.
Expect to pay US$48/year for 20GB. This is $4/month versus iCloud's $40/year for 20GB. Drive supports accounts up to 16TB. Google Docs storage does not count against your Drive, and retains is super-economical pricing. You can pick up 20GB of Docs for $5/year, 80 GB for $20/year, etc.
As expect
