How good are PHOTOFAST CR-5400 DUAL MICRO SD TO MS PRO DUO ADAPTER, Sony PRO DUO memory is geting very expensive and hard to get non fakes so I am thinking of changing over
No matter how many people tell you that they work fine, they can corrupt your micro sd cards (frequently, bye-bye saves), the adapter can simply stop working, the adapter can also cause your psp to stop reading memory sticks. If you use 2 16gb microsd cards, you're practically guaranteed corruption. There are a lot of potential issues in using one. I have a memory card reader with a memory stick slot that doesn't work anymore after trying to read the photofast. The photofast also no longer words, and neither do the 2 8gb microsd cards I sacrificed to the cause.
..but for the vast majority of people, they seem to work. Your mileage may vary.
For best results get an official Sony Mark 2 or Sandisk Ultra II stick instead. Sandisk regular sticks work fine as well, but if (like me) you were unlucky enough to get some slow ones, performance suffers. Never, never buy Lexar memory sticks, they are the absolute worst of the bunch. Far too slow for PSP usage.
