I just found this article very interesting. This blogger point out that Google is just playing number game.
The current rate of increase is at an average of 4 bytes per second
Now, we’re ready to do some basic math:
4 bytes / sec => 240 bytes / min => 14400 bytes / hr => 345600 bytes / day
If our goal is 3 GB and we’re going at a rate of 345600 bytes / day, it would take:
X days = 3,221,225,472 / 345,600 bytes
~ 9320 days => 25 years to go from 1 byte to 3 gigabytes
Ok, now we’re already at 2,693,144,200 bytes as of 4:30 PST, Feb 9, 2006. We’re now 528,081,272 bytes (503 MB) away from our 3 GB goal. So, let’s count how many days are left for GMail to become 3 GB.
X days = 528,081,272 / 345,600 bytes = 1528 days => 4 years
Because of counter running at Gmail website, we all think that we will get 3 GB soon, but in reality, it would take 4 years to come. Yes, that’s true 4 years.
