The reason apple build non-upgradable hardware has nothing to do with speed, it has to do with $$$.
It's the same reason the iPhone doesn't have a uSD slot unlike most high end Android and Blackberry phones.
Why put a uSD slot in a phone when you can charge 10x per GB for onboard flash storage and have a built in artificial product limitation?
