Hello Arnd,
Here are the results for the Kingston CF 2GB (Assy in TAIWAN). The one marked with (Assy in Japan) have another size, and probabbly other characteristics. Could the size be related to the number of open-au's ?

There could be any number of differences between cards from the same manufacturer if they changed the controlle chip.

I have not completely understood the logic that Linux uses to select the best transfer mode. Apparently, this card is able to do MDMA2, but is configured for MDMA0.

My interpretation of this is that the card uses a log-structured area for staging the writes here, at least in some cases. It needs to write all data twice to get it into the right order, hence the peak rate of about half of what it could get (6.5 MB/s).
As you go to more blocks, it needs to garbage-collect more often, but it does not get to a strict cut-off point like the linear measurement.

Nothing to see here, except for the page size, which seems to be 2 KB, i.e. relatively small.
Note that this test case is more useful with the --random argument: A lot of cards that can not efficiently do random access on most of the medium can actually do it in some area at the start.
Added to the wiki, thanks!

Hello Arnd,
I discovered the hard way that not all kingston cf 4gb are equals. When reading the back label, I saw differences in what seems to be a revision number.
I have here 001.AOOLF 005.AOOLF 006.AOOLF 018.A00LF 030.A00LF
They all have the same front label, except the 030 series which has a slightly different front label. I have attached the two labels.
I also have white (no label) CF 4G cards that we buy from pcengine.ch
I send you in separate messages the results of flashbench on them.
I am sorry I do not remember exactly the sequence of commands to execute, so feel free to ask for more info.
