Mega GP Mania

I've seen them. I'm choosing to stay out of them as much as possible.Have you not seen the OS topics? All the discussion of the PND format for this future device has leaned towards using it only for games and to use the repo for everything else.
Is the development cost of uSD significantly lower than eMMC? I'd expect it to be higher, if even just a few pennies for the connector. The actual costs of the chip itself shouldn't make a difference, whether uSD or eMMC that cost will be directly translated to the end user during production, nothing to worry about during development.That's not what I meant. I meant it would be cheaper for EvilDragon, and thus easier to produce.
The limiting factor isn't the card, it's the device. Just as the Pandora has a maximum theoretical transfer speed of 24MB/s (and practical transfer speed of about 16MB/s) the SoC chosen for the Pyra is going to have a maximum theoretical speed as well. The bus speeds for eMMC and SD will be identical, so the difference will be bus width, wherein eMMC is double that of SD (at least). Choose a good eMMC chip that is rated near the maximum bus speed and it will necessarily be twice as fast as any uSD card you might put in, regardless of how bleeding edge that SD card might be.Although it would be -possible- to put a 'fast' eMMC module in the device at twice the price of a 'normal' eMMC module that would be somewhat faster than the microSD cards of today, two years from now it will likely be slower than the 'bleeding edge' microSD cards on the market - and seem pathetically small
