When Gmail first came out we only had 100MB or 500MB with our emails, and sometimes you had to pay exuberant amounts for the upgrades. Google has spoiled us with their Gmail Services, I remember when it was launched years ago when they said you would never have to delete anything ever again, they were the first with 1 GB and just kept going up exponentially for a while and then they got to about 7 GB and still more then everyone else with the easiest email system to handle and most intuitive. Now they have really gone over the top and providing paid storage for huge amount of storage for a very low amount. Storage availability from Gmail has become so large that people have written lots of tools & scripts to make use it for online storage or back up, and now because of these numbers more scripts & tools will be developed. I wouldn’t mind paying $100 per year for 400 GB of storage, that’s a lot that can be stored or shared online.

Storage Upgrades:

• 20 GB ($5.00 USD per year)
• 80 GB ($20.00 USD per year)
• 200 GB ($50.00 USD per year)
• 400 GB ($100.00 USD per year)
• 1 TB ($256.00 USD per year)
• 2 TB ($512.00 USD per year)
• 4 TB ($1,024.00 USD per year)
• 8 TB ($2,048.00 USD per year)
• 16 TB ($4,096.00 USD per year)
