Right... So per your analogy ("Might be higher than a SD Card but it works for me.") it's not at all like driving an Indy/F1 car in a 20... or rather it is, except you're arguing for the Indy/F1* and I'm arguing for anything that goes 20mph or higher but costs considerably less...  Per your friend... you seem to be arguing he bought stuff he didn't need.  I'm saying I think SD cards basically give better bang-for-the-buck and otherwise satisfy the same needs.  (Cheapest 8gb SD I found via Buy It Now on eBay was $4 btw.)

I was just trying to point out something I'd observed, though.  I didn't realize I was entering such contentious ground lol.

*I'm not only saying go out and get a 300MB/s card - I'm saying that per transfer rate, SD is considerably cheaper.
