Default poor SD-card performance 0.79MB/s ?...what about a tweak?

my QTEK9000 reads the card at 0.79MB/s , according to PocketMechanic.
This is incredibly slow..
I just ordered 2GB x150 card, but I assume the speed will be the same,

is it not possible to somehow make the PPC read/write (much) faster ?
