Flash Cards and speeds

[Cyber Akuma]

I am extremely confused, I was performing performance benchmarks on my flash media and wound up with the exact opposite results I was expecting.

Cards that I was expecting to be slow were fast and vice versa. My cheapest card appeared to outperform my most advanced card.

Which is why I am asking this, did I even perform the tests right? Do these results seem accurate? Did I do something wrong? Am I just reading the benchmark results incorrectly?

The software I used was SiSoftware Sandra, as well a propitiatory little testing app for one of the cards.

I formatted each card before testing.

For the 2GB SD card, I tested it in both my laptop's internal flash memory slot and by a USD adapter I have. The Slot appeared to outperform the adapter so I didn't use it in my other tests (The MicroSDHC card though I did because it came with a different adapter).

I then tried filling my 2GB SD card with data and found that the results were more or less the same as empty so I didn't bother filling my future cards either.

Basically, most cards I just formatted then tested them empty in my laptop's internal bay.

I don't remember where I purchased my 2GB card, it was a while ago.
Its listed as an OCZ HI-SPEED 150x card, I expected this one to be the slowest but it appears to be the fastest.

This is the 8GB MicroSDHC card I tested:

Read speeds were VERY important to me on this card, especially random read speeds, so I reformatted it with 64k clusters instead of the default 32............ but it seemed to go SLOWER after that according to the tests I ran with the secondary program. Shoulden't larger file cluster sizes speed up access, not slow it down?

This is the 16GB Transcend SDHC card I tested:

This is the 16GB A-Data Turbo SDHC card I tested:
http://www.amazon.com/gp/product/B0010LPBRK
I was expecting this card to be faster than the Transcend but it was fairly equal... yet was still outperformed, and still was outperformed by the 2GB card.

I have uploaded a zip with .txt files of the tests I ran and the benchmark results here:

Can anybody please give me some input on this?

And where I can look up benchmark results for large SDHC and MicroSDHC cards? I tried googling it but mostly just found user reviews and tests from 2007 on cards that are obsolete.

Should I reformat my card to 64k file clusters to maximize performance in digital video cameras?

That didn't really explain anything
