I reccomend this:

I use that one, and it has no slow-downs ever

 

This is what I have, I've never had slowdown from it with my Acekard 2i.

 

I recommend ADATA.
I bought an ADATA 4GB Class 6 MicroSDHC card from Newegg, it was actually one of the cheapest of ALL 4GB SDHC cards too, and it's worked flawlessly. Absolutely NO slowdowns or long save periods.

The slowdowns happen on cards with low Random Access and Read speeds. The Class rating is for WRITE speed only, but it stands to reason that something with a high write speed will have a higher read speed as well.

 

Okay people, wake up call,

* Class speed defines MINIMUM writing speed. It defines the slowest writing speed possible under normal circumstances. When I said normal I mean under ideal condition and room temperature. Class speed has NOTHING to do reading speed. While it correlates with reading speed, there is NO definite relationship between them.

* Even if reading speed is increased, it does NOT translate into increased performance for flashcart. In flashcart we are looking for random access speed. Reading speed everyone is referring to sequential access speed. Sequential access speed means data is being read from point A to B to C to D in order. It is an important factor camcorder, camera, computer, etc. Random access speed on the other hand, is an important factor for flashcart. In random access speed, data is being read from point A to D to B to C in RANDOM order. Reading speed does not tell us random access speed. Again, while reading speed tends to correlate with random access speed, there is NO definite relationship.

* Class speed is rated by manufacturer. It is NOT confirmed by SD card association. Therefore it is possible that some manufacturer lie about class speed.

* While there is no conclusive evidence behind this, people have reported that higher class leads to higher chance of data corruption.

 

I've used 4 gig Class 6 A-data microSD cards exclusively, for three years.
One of them got corrupted in my old M3 simply, but that was the only time.
They're my best recommendation.

 

I also have this exact card. No problems here.

 

hey guys,

i've been having a problem running certain games that are confirmed working with AP patch. games like 999, and golden sun (J) both crash while running with AP although it is confirmed working with AP.

i have a kingston card that came bundled with Acekard 2i from realhotstuff, some kingston crap card that has worked with most games, but not with games with AP.

if i buy this card http://www.amazon.com/gp/product/B0013DXVY...m=ATVPDKIKX0DER will it 100% work with AP enabled in those games that normally crashed on my kingston card? if you don't know, could you recommend a card from amazon that will 100% work with AP patch? thanks.

thanks guy.
