# calculating storage based upon on eps?

If an organization collects an average of $20,000$ EPS over eight hours of an ongoing incident, that will require sorting and analysis of $576,000,000$ data records. Using a $300$ byte average size, that amounts to $172.8$ gigabytes of data.

I'm not clear how this $172.8$ was calculated. I know 576,000,000 was taken by multiplying 8 hours into seconds. Should i divide the $300$ byte average size? Please help.

$$576000000\cdot300=172800000000=172.8\cdot10^9\;.$$
A gigabyte is usually defined as $10^9$ bytes, though an alternative definition as $2^{30}$ bytes is also in use. –  joriki Nov 8 '12 at 9:25
