Recently I was watching Ocean’s 13 which passed the time reasonably pleasantly. There was a supposedly awesome computer which our handsome heroes had to overcome called “The Greco”. Apparently it stored its data “in a field of Exabytes”.
This got me thinking about all the different storage metrics and the fact many of us can get them confused. I decided to pop the following list down for your viewing pleasure…
|bit||b||Fundamental unit of data storage|
An Exabyte is seriously huge! If you take it that DVD quality video requires a bandwidth of around 5Mbits/s plus about 0.45Mbits/s for its audio that gives a total bandwidth of 5.45Mbits/s. This equals 0.68MB/s. Now an Exabyte is a million million MB so divide that by 0.68, then by 60, then by 24, and finally by 365 and the answer is:
An Exabyte would be able to store 46,632 hours of playback time!!
