Memory Stick Duo adaptor for Memory Stick and Memory Stick Pro

Product Information

You may find after reading all the information presented here that you have no need to go beyond ~200, ~400, or ~500 GB in size based on other usability factors I will discuss below. There are more cards than I have shown here but for the most part the taxonomy above will at least allow you to select and try different types of cards.

Sony announced on June 1, 2009, that M2 support in Sony Ericsson phones would be dropped in favor of microSD. [31] NOTE: If you plan on using only a single MicroSD card in a Dual adapter, place it the slot labeled "1" (top slot). While I don't have any experience with them directly they are likely easier to work with since they use only a single card for formatting and therefore would be only a physical adapter (as opposed to circuitry which combines two cards into one). If you have or can get a deal on a single MicroSD of the capacity you want (say 1x 256 or 512 GB) you might be better off just getting one of these single adapter cards. The below has all been validated on this device running currently running 6.61 ME 2.3, though the vast majority of this should work on all of the standard PSP models using ME or PRO. There is a bit more detail below regarding FW versions (which are really beyond the scope of this guide). Try a different CFW (though I doubt it will make a difference as long as both support high capacity).

This process simply entails re-formatting your card through the PC. After putting your PSP in "USB Connection" mode and seeing the drive letter appear in windows we need to reformat.

Additionally, all my tests were done with MicroSD cards up to 200 GB capacity (because I got a good deal on them). This means the largest high capacity setup I have personally tested is 400 GB. Theoretically, the information in this guide should be attainable for MicroSD cards of 256 GB, 512 GB, or even 1 TB in size. Practically however it may be that the adapters on the market today have a limitation or that the CFW will not indeed support such large sizes. I will leave it up to others who have the available hardware to test this. Once the cards were formatted however I was able to remove the MicroSDs and place them in any card and they all appeared to function normally. The exceptions here are #1 (the genuine PhotoFast which wouldn't support cards higher than 32 GB) and #6, which seemed to have no issues with 2 x 64GB but would not read my 200 GB cards properly.

The only difference between SDHC and SDXC cards is the maximum storage capacity and default file system format.

If it doesn't show the correct space then you won't be able to continue on with the next stage of configuration. You may opt for a smaller card and use CSOs to save space. Comparable to the speed differential, many games can be compressed considerably from their ISO forms. With all the cards (again, with the exception of #1) I was able to achieve a 2 x 64 GB cards (using the process described below). If however you can't get the PSP to recognize the card with all space you will likely need to get a hold of another adapter, MicroSD card, or possibly CFW.Based on this I would have to recommend #5 if you plan to only go up to 128 GB of memory. Unfortunately I couldn't get this card to reliably detect my 200 GB card and so #6 was the best choice and the one I would continue to recommend out of my tests. You should dissconnect from the USB connection and restart your PSP several times to ensure that the card continues to be detected.

As we can see from the picture above we can break down these cards based on several identifying factors.If you had a "Format completed" message on your PSP and #1 above is true you can likely stop here and just start using the card. You can manually recreate this structure by copying it from another working card that formats successfully in your PSP.
