Writing to any memory card with the card reader is really slow for me. In this same machine with Windows XP it's reasonably fast, and I've noticed that the LED of the card reader blinks at the same interval until the copy finishes.
On Linux it blinks fast for a moment, then slow, then fast again, then it stops for a while... The transfer lasts much more and it uses a lot of CPU.
Does this happen to someone else?
