I have tried it with 2 128gb but it doesn't work. I also tried with 128gb and 32gb and it doesn't work. Now, for other sizes, I don't know. However, one of them, the 128gb, works and gives 116gb.

I prefer this product. For those who still use the PSP, this is just what you need. It is not necessary to get 2 micro SD cards SDHC, just get one and it's enough. I recommend getting a micro SDHC with a maximum of 16GB because the PSP may not read a card with 32GB. I tried it on the PSP 3004 and I have written games, transferred these games onto the micro SD and saved them on an adapter. It does its job very well. You can also use it to store photos and videos. This adapter can be used for many purposes and on other devices as well, such as a mobile phone and computer, as long as you have a USB card reader. Everything can be stored there too.
