Ok, thanks!
Are you using UDMA mode?
How can I find out ? I put the card in the slot and let linux decide.
In the list above, you can see the * next to the active mode. The card is evidently using UDMA5, meaning it can get up to 100 MB/s in terms of interface speed. This makes the 4 MB/s maximum throughput even more disappointing, but means that your host system is able to drive cards in very fast modes.
A lot of cards apparently only support the slower PIO modes, and with a PCMCIA adapter, you would only get pio0 with 3.3 MB/s maximum interface speed.
