Not a very scientific approach, but while migrating files from internal storage to the sd card, I noticed it taking a lot longer than moving the same sized files from my comps hd to the sd. The same file from my comp took noticeably longer to finish transfering to the internal storage. An ~800 mb file took nearly a minute longer. Also, the music loaded on the sd card is much more responsive in the stock player. The audio I had loaded on the internal mem didn't take forever to load up to the player, but I did feel it was a bit slugish. I'm always blown away by the size of these micro sd cards (and 32gb on that little thing, are you kidding me!?); but I, in no way, expected the read/write to be faster than whatever they've shoved into the inc for internal memory. I'm really pleased with the new card, but can't help to feel a little disappointed in the inc's memory speed. Anyone else having a similar experience? Anyone out there know the read/write speed of the internal mem?
