I really need help as i am a newbie in the reading and writing speed of the memory cards... (the performance index on psp 1000)

as i mentioned, i have a psp 1000 (phat version)

i wanna buy a 8gb card...

with the budget i have

1) i can go for sony memory card m2

2) i can go for cr5400 with 2 x8gb sandisk micro sdhc


but all i want is speed performance and longevity(quality)... i dont really mind about the storage space... i scared lag on gameplay

all i wanna say is that if the 2nd option based on the speed performance and longevity is almost the same as the 1st... i think i will go for second option.. but so far i am stuck and i dont understand which to get... if the the points stated are very different among those 2 options, i will go for option 1

so pls help me!!! T_T ...

thanks yea

good question, i'm interested to know the answer too. if the second option is worth it, i also go for it

i also have a phat version

and last week i bought 8GB sony pro duo magic gate
