It is worth pointing out that "same brand of card" is approximately
meaningless. Up until a few years ago I oversaw the company I worked for's CF
cards. Every new shipment had new geometry, ID strings, performance, etc even
when it had identical labels on the outside...
I don't doubt that soft updates help, but I'm not sure this is a 100% fair
