Wow, they look really good!

I'm sorry if I missed an explanation, but why exactly does the 120GB struggle with write speeds?

Because 1/2 the output elements gives half the bandwidth.
There is almost no difference between 240GB and 480GB because the bus is already saturated at 240GB.

Aha, I figured that was what it was, but wasn't sure. I don't remember seeing other 120's do so heavily so that's why I asked.
