ZettaByte

               Around 10 years ago (in 2003), when i first bought 128 kilobyte storage mp3 player, i was very happy that i had the highest storage capacity mp3 player that the company selling at that time. I was so crazy about the storage, i bought the first Apple ipod 60gb (in 2004), which i rarely used. I knew KB, MB and GB only that time. In 2009 i bought my first TB hard drive and so on continued.. Now i am hearing the PetaBite, ExaBite humongous storage capacities, which are not for the individuals but the companies/GOV organizations like Google, NSA, FAA, Amazon...etc to store the data, which may be structured or unstructured data.

       

ZettaByte storage is 10²¹ or 2⁷⁰ which is Sextillion in currency.

1 ZettaByte =  10²¹    = 1,000,000,000,000,000,000,000
