I guess it's the same as with the cards, lots of crap out out there.

I have one, but how does that help me figure out the current draw before
I buy the USB drive?  Besides, these meters are way too slow to show the
dynamic peaks.

It's at least a 30% difference once you figure in that the adapter
wouldn't really be needed in the first place and even more when you
realize that it actually hangs off a SDIO-to-USB bridge on the rasPi.
That's two bridges that do absolutaly nothing useful but burning power.
