transfer-speed

I went and bought an expensive SanDisk Extreme III SDHC 8GB class 6 chip.

However when I dump data from the card to the machine via USB 2.0 cable, its only getting 5.0 MB/second maximum according to Windows 7 disk explorer. It still can take up to 20 minutes to dump the card when its near full.

This is so far below the rated 20MB/s transfer speed I can't believe it.

Is this normal or might I have a defective chip?
