# 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.

$$576000000\cdot300=172800000000=172.8\cdot10^9\;.$$

but thats bytes not GB? which is 160.933 GB. not 172.8 –  asadz Nov 8 '12 at 9:24
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
if i do a google convert using convert 172800000000 to GB it gives me 160. –  asadz Nov 8 '12 at 9:26
If your concern is with different definitions of a gigabyte, you should ask about that, and this wouldn't be the appropriate forum. Here you asked about how the number 172.8 was calculated, and I answered that question. –  joriki Nov 8 '12 at 9:28
oh i got it google is using 2^30 not 10^9. I got it:) thanks:) –  asadz Nov 8 '12 at 9:28
