Palm T|X Flash Memory Speed

I use Mapopolis (no longer available for sale) and was wondering if a high speed flash card would help. When I had my previous E2 it had a memory limit of 1GB, but with the T|X I can now use 2GB. This card was on sale for $14 at Staples, so I figured it was worth a try. There are lots of posts about card speed, measured with various utilities (but the numbers appear unreliable). I am a big fan of benchmarks that represent real world situations. Copying from my PC to this card (with my USB2 reader is faster than my old 1GB card). Even more important a nvbackup of my Palm was cut from 14 minutes to 4. So clearly the Palm T|X can benefit from at least this level of speed. Kind, of wish I had gotten the even faster card to benchmark :) Mapopolis seems more responsive, but it is a lot harder to benchmark. I've got all the US maps, and all the applications I use commonly on the card as well as an nvbackup image. This way if I have to do a factory reset all I need to do is reinstall from the card.
