What comes after Terabyte?

 
Here is the complete list:
 
1 Byte = 8 bits
1 Kilobyte (KB) = 1024 bytes
1 Megabyte (MB) = 1024 kilobytes
1 Gigabyte (GB) = 1024 megabytes
1 Terabyte (TB) = 1024 gigabytes
1 Petabyte (PB) = 1024 terabytes
1 Exabyte (EB) = 1024 petabytes
1 Zettabyte (ZB) = 1024 exabytes
1 Yottabyte (YB) = 1024 zettabytes
 
 
I wish that I have a NAS with 1PB storage and 1TB or better I/O rate.
 
What would you do if you have such a large storage?
 
 
Cheers.
