WTF is going on with my 4k random writes?? They are too low compared to those I see from other people here...

Another thing I see is that the Samsung 8GB Class 2 is faster in the 4k random writes than Kingston 8GB Class 4 which I currently run the NANDroid from... I'm gonna swap the cards and do some testing to see if the system becomes faster/smoother and report back later...
