[General Accessories] Cyber Akuma:
I hope I posted this in the right section, I wasn't sure where a question about MicroSDHC cards would go here.

By the way, I live in the US.

I have been Googling this for days now, and coulden't find any conclusive information, especially since most of it was from random tech blogs and not respected tech/research sites.

I am looking to buy two MicroSDHC cards to use in a Photofast CR-5400 ( http://www.amazon.com/PhotoFast-CR-5400-MicroSD-Adapter-Dual/dp/B001I0T92Q ), speed and performance are pretty important as I will he handling a lot of data through it.

First of all before I start, anybody familiar with this adapter? Where would be the best place to purchase one so I don't wind up with a Hong-Kong bootleg? Ive had trouble purchasing flash memory online before from places like Amazon or Ebay where the memory was a bootleg that didn't perform anything like the real thing.

Now, I know that Memory Stick Pro DUO devices are generally faster than SD or SDHC devices, but AFAIK that device sets them up in a RAID 0 configuration so I am hoping that will help, this is why im trying to get the best performance MicroSDHC cards I can afford. And trying to get reliable information on these things has been a lesson in confusion.

First of all, it almost seems like the class speeds don't matter. Ive seen benchmarks that showed class 4 or class 2 cards outperform a class 6. Whats the point of these classes if they are so meaningless? How can a class 2 device have faster write speeds than a class 6? And is this classification only for writing or reading too? Why are the "ultra" models of some cards, which are supposed to be very high speed, listed as class 4?

Second, I heard that there are other variables that usually are not listed anywhere, such as Random Access Times, which from what I read are internal processes taking place in the card itself rather than having anything to do with the card reading/writing to whatever it is plugged into. And I really have no idea what else could be a factor.

I was looking at THIS Transcend card ( http://www.newegg.com/Product/Product.aspx?Item=N82E16820208475 ) mainly because the previous 8GB version ( http://www.newegg.com/Product/Product.aspx?Item=N82E16820208453 ) seems to be the best one you can possibly get, the 8GB model is class 6, rated as very high speed, and even has a low Random Access Time. But that doesn't mean that just because the previous model was good, the next one will be of the same quality, and on top of that I don't know if it'll even matter in that Photofast adapter or not. Not to mention its kinda pricey, don't forget that I will need to buy two as well as the adapter (though since the 16GB Memory Sticks came out at over $200 and they are barely around $100 now, and the 32GB still isn't out yet, I am going to assume it will still be at least $50 cheaper than just buying a 32GB Memory Stick............ when they come out).

So what would you recommend I do? Where can I find information that makes sense of this? Where can I find good benchmarks/testing done on these cards that on top of speed measures the other factors as well? Where would be the best place in the US, retail or online, to purchase such a 16GB MicroSDHC card for the best price?

Thank you for your time.
