There are some simple programs that benchmark performance of Flash cards
inserted in the Newton. I don't recall the exact numbers, but someone here
can post their results.

The PCMCIA performance of the Newton will be lower than the iPaq as the
SA-1110 also integrates a PCMCIA controller vs. the SA-110 having to talk
to the Voyager parts.

The PCMCIA interface on the SA-1110 is essentially another chip select off
the Static RAM interface built-in to the processor. As a result,
additional bus cycles aren't required to transfer data to/from the CPU.
The PCMCIA interface on the SA-1110 however does not support any kind of

I think this is a more complicated problem as the amount of free-heap and
other software centric issues come into play.
