SD cards

[Jim]

I know this isn't really a linux question, but I don't know who else to 
ask and I haven't yet found an answer online, but I'm still looking.

I'm looking at buying a micro sd card and have found some UHS -I cards 
that advertize 180 MB/s read speeds and 130 MB/s write speeds,  I've 
also read that UHS - I is supposed to have a maximum speed of 104 MB/s.  
Are the card makers guilty of false advertizing, or is there some way to 
get around the 104 MB/s limit?


thanks
