Ive had my Acekard 2i for awhile now and I did a lot of research before purchasing it. Up to this point it has work completely fine, but once I started playing pokemon white I started to experience problems with lag when I access the items in my bag, and try to drag and drop pokemon in my pokemon box. I never seemed to have any trouble with other pokemon games up to this points so I'm wonder what the problem could be. I was thinking the only logical reason behind it is that since its a newer game maybe it is more demanding on the read speeds of my micro sd card and my micro sd can not keep up with it like it could the older pokemon games. I am currently using a sandisk class 2 16gb micro sd which is the first sd card I have ever purchased. Before purchasing the sd card I did some simple reasearch in what was important when shopping for sd cards and I didn't know anything about the classes or what they ment. At the moment it seemed like brand name was most important because multiple customers were complaining about the failure rates of off brand sd cards. I also remember looking into a forum that said that the speed of the sd card shouldn't matter for the performance of the Acekard 2i. I am running AKAIO 1.8.6a. Now, the main reason I created this forum is to ask whether or not I should consider purchasing a new micro sd card for better performance. If I shouldn't buy a new micro sd card, what could be the problem behind my lag? I purchases an Acekard 2i and a micro sd for my cousin, and he chose the micro sd. He chose an A-Data class 10 16gb which didn't cost too much more then the sandisk I purchased. According to him, he doesn't have any trouble navigating through the items in his bag or the PC box in the game and the game runs as smooth as it possibly can. This is the main reason why I believe the micro sd is the problem. If the micro sd could be the problem it wouldn't be much of a hassle to buy a new one, since I just got a new cell phone that I wanted to upgrade the sd card for, and im sure that if I wiped my 2 gb sandisk I had now and used it for my cell phone the read and write times shouldn't matter for playing music. I thank all those who spent the time to listen to my ramblings and offer their assistance.
