I can't see why you'd want to use a SD-card for playing your games directly from. With maximum speeds (class 10) of around 10MB/s it is too slow compared to an external HDD.
Actually this isn't really true. The 10MB/s of a class 10 card refers to the write speed which is slower than the read speed but more important on capture devices. Many of the higher class cards have read speeds a fair bit higher than that. Ontop of that because the ports on the back are USB2 you'll be limited to about 30MB/s even if you connect to a 500MB/s SSD. Probably also limited to that on the SD card slot if, as it often is, it is done via USB2.
So I doubt there'd be much of a performance boost going from a high end SD card to an external HDD. It does make more sense given the gap in $/GB but.

Yes, speeds are normally much higher for read, but the classes do refer both to read AND write. Read/Write must be over 10MB/s for a class 10 specification.
It is still, like you state, a pretty bad choice in regards to money to GB ratio.
