However it should be noted that there is confusion floating around about those terms. The problem is that 2^10 is approximately 1000. Therefore sometimes people use factors of 1000 and other times people use 1024 in very similar contexts. This can lead to confusion and odd ratios.
What looks like it happened in this case is that someone consistently used factors of 1024 rather than 1000, found that a petabit is 128 terabytes (which technically should be called tebibytes), and then miscopied 128 as 178.
