It's good that things are a little faster, but this isn't the way they should be. Transfers to/from the reader should be VERY fast, and they are now for me. Most tasks are finished before I have time to check on their progress. Reading the contents of the card takes just a couple of seconds.

You might keep working with the card. Information about the card interaction is hard to come by, but this delay hints to me that Windows is repeatedly trying and failing some simple operations on the card, fanatically trying to write, write, write in a manner harking back to MS-DOS roots, where you could actually see this happen on the floppy disks of the time, with DOS actually telling you that it was busily retrying the same operation 50 times before deciding that it really wasn't working.

Make sure you've got that card as flat (empty) as possible. Use Diskpart to knock down all partition information. If the reader recognizes the card, you haven't done enough. Get it to the point where the reader won't do anything with the card without formatting it first.

This was a pain for me, but I haven't had a lick of trouble with it since.
