And which one would you rather have and why?
I'm guessing the 1024kb PCM is for later models and has additional features.
All I know is that it takes around 2 minutes to read a 512kb PCM and 4 minutes to read a 1024kb PCM.
So at this stage the 512kb PCM = WIN.
I'm asking because I'm going to swap my PCM for another hopefully this week and want to know which PCM would suit me better.
