So I had ask someone what PB stood for considering Microsoft can now hold apparently 2.5PB a month with its new Event Hub.
It stands for Petabyte which is 1024 Terabytes but what does that mean in laymen's terms? This picture explains it quite well but some more facts by computer weekly are bellow;
- If the average MP3 encoding for mobile is around 1MB per minute, and the average song lasts about four minutes, then a petabyte of songs would last over 2,000 years playing continuously.
- If the average smartphone camera photo is 3MB in size and the average printed photo is 8.5 inches wide, then the assembled petabyte of photos placed side by side would be over 48,000 miles long - almost long enough to wrap around the equator twice.
- One petabyte is enough to store the DNA of the entire population of the US – and then clone them, twice.
- If you counted all the bits in one petabyte at one bit per second, it’d take 285 million years.
- If you counted one byte per second, it would take 35.7 million years.
- It would take 223,000 DVDs (4.7Gb each) to hold 1Pb.
- It would take 746 million 3.5-inch high-density floppy discs (1.44Mb each) to hold one petabyte; 746 billion floppy discs weigh 13,422 tonnes (if each one weighs 18g). This is just under the size of two Type 45 destroyers, such as the newly built HMS Duncan, which has just left the Clyde
- Estimates of the number of cells in a human body vary, but most put the number at approaching 100 trillion, so if one bit is equivalent to a cell, then you’d get enough cells in a petabyte for 90 people – the rugby teams of the Six Nations.
but how much is that really? We put together this series of stats to help you understand just how much data that really is.
