Aha, I changed the combo reader for a single-slot Kingston reader
(It's actually PCMCIA with an adapter) and now I'm getting just over
2.5 MB/sec with the same test.
I'm a bit surprised because Sandisk's advert for CF cardreader,
they say it's good for 16MB/sec, so I thought there would be
nothing noticeable between any readers at 3MB/sec.
For the sake of comparison, on my fast Linux machine with a firewire
CF card reader, I get 3MB/sec read and 4MB/sec write on that card.
