hi, i only tested on 8GBx2 mobile Ultra sandisk microSD, becoz single 16GB microSD is still very expensive. i guess after chinese new year the price will drop to very acceptable level. Some forumers from the internet really tested on 16GBx2, not sure how is the performance for 32GB. but performance for 8GBx2 microSD is much more faster than original 16GB sony especially more than 10MB/s write speed.
