This is a very basic question but I've not been able to find an answer for it - does reading an SD Card through an adapter, either like a mini-USB pen or a micro-SD card being read through an SD Card adapter, slow it down? I just wondered as I have some spare mini-sd cards I've been using as storage and use them via USB adapters and the like. It leads me on to my other though, which is why would speed be capped around 500kb/s when advertised speed is in the MB/s range? I noticed this when copying information around and the speed never rose above 500kb/s but shouldn't it have been faster? Where is the bottleneck? The card, the adapter, or something in the computer? Cheers.
