Perhaps I am overlooking something, as I don't know a ton about how android actually works. But I was looking at the speeds that people are getting with Verizon 4g LTE Service, which are well over 10mb/s. Then i was thinking, In order to write stuff that fast to a SD Card you would have to have a fairly nice SD Card, when i looked it up i saw that most Android Smart phones have around a 2mb/s SD Card. So I am thinking it stands to reason if you are trying to download stuff at a speed of over 10mb/s to a SD Card that can only write at a speed of 2mb/s. There is a bottleneck there. Can anyone tell me if this would actually bottleneck your speeds? Or what kind of SD Card the HTC Rezound Ships with? EDIT: I know that many things like aps are downloaded right to the internal storage in the phone, but if you are like me and download music and videos to the sd card. This could be a problem.
