Summary of the estimate of memory space occupied by the information worldwide, stored in various storage media, in the year $2000$

In the above graph, for any media of information  storage, the figures in the brackets denote the amount of memory space occupied by the information stored worldwide in that media of information storage. For example, the memory space occupied by the information contained in Music CDs worldwide is $55 \; \text{TB.}$

Note:

  1. $1$ Tera Byte (TB) of memory space $=10^{12}$ Bytes of memory space.
  2. All storage media are classified into four categories  – Optical, Paper, Film and Magnetic

If the information contained in each X-Ray occupies $30 \: \text{MB}$ of memory space on an average, and by using a new technology each X-Ray is now stored in magnetic media that saves $60 \%$ of the memory space required, what is the total amount of memory space of magnetic media that saves $60 \%$ of teh memory space required to store all the X-Rays available in the year $2000$. ($1\: \text{MB}=10^6$Bytes of memory space)

  1. $10,170\:\text{TB}$
  2. $6,780 \: \text{TB}$
  3. $1,703,170\:\text{TB}$
  4. None of these
