Sony 4 GB Memory Stick PRO Duo Flash Memory Card MSMT4G

Needed more memory as backup in case the original fills up before we can download to a computer and then build some DVD files. Got the highest speed class 10 to make sure we could also do video. Turns out some adapters we had cannot handle anything higher than class 4. But we got passed that.

I bought it for my PSP-2000 and it works with no problems. As other buyers have noted, it has ~14.9 GB usable space. Data transfer between my computer and my PSP was ~8MB/second using a USB cable.

I've read a few reviews warning about counterfeits. I bought the 16GB MKII Pro Duo from OneStopShop via Amazon and got the real deal. I loaded 12GB of data onto it to verify it worked and then ran a CRC32 check on them to make sure the data didn't get corrupted upon transfer.

I bought this for my Sony PSP 3000 and it is an awesome deal. I still want to buy a 16gb, but this is good for now... the only complaint i have is that the first one I had sent to me was defected and the memory stick was being really weird so I contacted the seller and I got a new one while I returned the defected one.

there is no case for it. that's why I took one star off. I am using it for my psp 3000 and works great. It says 15gb free, but all memory cards will have some memory space missing...

This 8GB memory card works well with my PSP. I have had it for 2 months and do not have a problem with it.
