The question is in the title really. I noticed that sending files to my new 4GB miniSD card was taking an age so I done a quick test.

I created a folder and put in a few 3gp files totalling 99.8mbs, then I sent it to my SanDisk 2GB card via the mobyMemory card reader that came with it, this took 1min 51secs.

Then I sent the same folder to my MobyMemory 2GB card which took 1min 55secs finally the same folder was sent to my new 4GB card which took 7mins 43secs.

I wonder if the slow transfer rate may affect play back of high bitrate files, movie or music, or have I just got a duff card?
