Hi All, I'm looking for a 32Gb SD card for the Droid X. Is there a type/spec in a card that I should be looking for that will give me the best performance? Also, I have a question on Droid X memory usage. Does the Droid X differentiate between the internal 8GB and the 16GB SD card? That is, does it sum up total memory or use the two memory blocks for separate purposes. Thanks.
