Just trying to make decision what speed grade SDHC card should I be buying? Most 8GB that are priced around $70 are Class 2, and Class 4's start around $100. Currently I'm using a "regular" (non-SDHC) 4GB SD card with "unknown" speed... and it seem to be plenty fast when reading data. But the writing seem quite slow, taking like 10-15 minutes to write a single 300MB file into it when connected via USB cable to the PC. (Yes, PC port is USB2.0.)

I have seen some speed test numbers here about speeds of different cards, but I do not remember seeing anything about write speed of different SDHC class cards? Would the Class 4 be faster than Class 2 to write to, when using the patched SDHC kernel in N800?
