When you reach the limit of free storage (i.e., 1GB for Picasa Web Albums, 2.8GB for Gmail), consider this your overflow solution. Plans start at $20/year for 6GB (yes, $5 cheaper than before), with larger plans ranging up to 250GB.But if you are not that serious just create another google account for free and get another 3Gb of space.
Now, if you need more storage for any particular application which is part of the shared storage program, you can buy some. “With a Google shared storage plan, you won’t have to worry about deleting files, pictures, or emails. After purchasing a storage plan, some of your individual Google services (e.g. email and photos) will share a single new storage space,” Google’s page reads.
Another major fact is that Google has increased its 6GB storage plan from $1 to $20 due to customer rush.
