I'm probably missing something here, but why do you need an SD adapter? Can't you use the SD card slot that it comes with? Or do you want more than one SD inserted at a time?
I would guess that the OP wants to use a memory card that will not stick out when it is inserted into the slot.
In theory, a half-sized adapter with a micro SD card might do the trick.
We simply don't know anyone who has actually bought one and tried it.
Ah, I see. But if it's half-size, it'd still have to stick out a little bit in order to remove, since it's not a spring-loaded slot, right? If it were flush, then you'd need tweezers to take it out.

I have a 64 GB Cruzer Fit with 3.0 USB that I use for my car--very low profile. That's a good idea.
