Patriot EP 2 Gb SD - No problems
RiDATA 2 Gb SD - No problems
Kodak Picture Guard 128 Mb - No problems (not rated but a VERY fast card)
PQI Hi Speed 45 256 Mb SD - No problems
Ultra 512 Mb SD - No problems
Transcend 16 Gb 133X CF - No problems

I'd be even more interested in having speed benchmarks for various cards. As far as I've read all standard SD cards will work, but you need to avoid the new SDHC cards since they won't work unless you use one of those hacked ROMs that provide WM6 capability. I'd start a card speed database if we could settle on a piece of software for testing so we have something that will provide consistent results across the board.

I use the "Removable Storage" module in SiSoft Sandra XII Lite, since it is free. To read the SD memory cards I use my Dell notebook's SD card slot or an SD card adapter installed in a USB 2.0 port. For the CF cards, I use a USB 2.0 CF card reader. Here's an example...

PQI 256 Mb Hi Speed 45 SD card:

Read Write All data is in Kb/sec on 512 BYTE files
765 46 Internal SD card reader
95 21 Phillips adapter USB 2.0 attached SD reader
90 45 Phillips SD card adapter attached to a 4 port USB 2.0
ExpressCard slot adapter

As you can see this points out the problem with benchmarking... you mileage will vary depending on the setup. For some reason the Dell notebook (Inspiron 1520) is much better at reading SD cards from it's built in SD card reader than it is from using an SD card adapter hooked to a USB port or even my Frankenstein setup where I have a 4 port USB 2.0 adapter installed in my ExpressCard slot.

The file size used for testing also matters... this data is from very small files... for the last test shown above the same results on 64 Mb files is:

Read Write All data is in Kb/sec on 64 MEGABYTE files

7646 6554

So if we could decide on how to do it, I think it would be worthwhile.
