I wanted to know if anyone knows the following: With the dual Micro SD to Memory Stick Pro Duo adapter, do the Micro SD cards take a performance hit or does the adapter simply "pass through" , and if not what is the maximum memory speed that the PSP can physically handle? To rephrase: What is the maximum read/write capacity of the PSP's Memory Stick Pro Duo Card Reader in general? I want to put in 2x 32 GB Micro SD cards in a dual micro SD to Memory Stick Pro Duo adapter and wanted to see if there was a real benefit to going with the 30 MB/s Sandisk Ultra UHS-1 32 GB Class 10 cards or if the standard 10 MB/s Class 10 cards out there are adequate? My rationing for all of this? Why waste the extra $ on the faster cards if you don't need to? For those who may also be interested in this - Best Buy has the 32 GB Sandisk Ultra UHS-1 Class 10 30 MB/s cards on sale during Black Friday for $17.99. At roughly $40 to upgrade your PSP to 64 GB (59 GB formatted), it's a no-brainer..
