How to tell if I bought a fake Sony Memory Stick

Hey guys. I got a 16gb memory stick pro duo yesterday and for some reason, the transfer speed seemed slower than my old 4gb one. They're both magicgate supported and mark 2.

I did a test and with my 4gb one, God of War Chains installed at 5 min, while my 16gb installed it around 7 min.

I checked online on how to tell a fake from a real one, and mine does say its magicgate supported. But I don't know why it's slower?

Anyone else experience something similar, like difference in transfer or install speed when you upgraded to a bigger memory stick?

Just check the back of the memory card you should see something like MS-MT16G.Devil-Itachi
