Log Math

100,000 log messages / second x 300 bytes / log message ~ 28.6 MB
      x 3600 seconds  ~ 100.6 GB / hour
            x 24 hours ~ 2.35 TB / day
                  x 365 days ~ 860.5 TB / year
                        x 3 years ~ 2.52 PB

Oops! Now you know what is a petabyte.
And, BTW, you also now what is a trillion – of log messages.
