I have decided its time to replace my aged card reader in the computer with something USB3 back to the internal port on the PCIe card (its an old computer)

I like my current USB2 reader because it only uses one drive letter, and only reads one type of card at a time. The last few readers I have put in computers for friends have wasted 4 drive letters on a multitude of useless card slots so they can claim a large number for "X in one" reader.

I have a lot of other drives and dont want to deal with constantly disabling devices like I have to do for the slots in my printer and my external HDD docks, so ideally a reader that just had one slot and just did SD cards would be great, a USB3 passthru for the other connector would be needed too.

But all I see take an absurd number of dead memory card formats like xD and memory stick and compact flash.

Anyone seen anything nice and simple before I start hacking a blank drive panel with a slot and epoxying a normal card reader to the inside of it?
