Among the staff have asked me how can know the size of the storage, sometime if he want to buy external harddisk. So to answer the question after this, i will asking him to read my blog

If you thought you knew enough about computers and could challenge any byte sizes, think again. How much do you know about data sizes … your hard disc is 60 Gigabytes, the supercomputer analyzed 2 terabytes of data in a short time … but what is beyond that?

• 1000 Bytes = 1 Kilobyte
• 1000 Kilobytes = 1 Megabyte
• 1000 Megabytes = 1 Gigabyte
• 1000 Gigabytes = 1 Terabyte
• 1000 Terabytes = 1 Petabyte
• 1000 Petabytes = 1 Exabyte
• 1000 Exabytes = 1 Zettabyte
• 1000 Zettabyte = 1 Zottabyte
• 1000 Zottabyte = 1 Brontobyte – that is a 1 followed by 27 zeroes

So ideally and more accurately, it should be like :

1,024 Byte = 1 Kilobyte (KB)1,024 Kilobyte (KB) = 1 Megabyte (MB)

1,073,741,824 Bytes = 1 Gigabyte (GB)

1 Gigabyte (GB) = 1,024 Megabyte (MB)
