What is bigger than a Saganbyte?

Answer 1

PiB(Pijabyte)= 1024 SB

AB(Alphabyte)= 1024 PiB

KB(kryatbyte)= 1024 AB

You can go on and on but none of us alive will ever see a geopbyte of memory.
it's quite simple to deduct, the byte scale goes up like this:

103

106

to 1024 which is a yottabyte, just keep it up by 3 to saganbyte and you'll get the result

Answer 2

1024 Sagan bytes= 1 Pija bytes
