My Extreme PRO is SLOW

I recently bought from a sandisk extreme pro SDHC 8GB file. When I tried to run a benchmark, I only get 19MB/sec tops. FAR from the advertised 45MB. 

I already used Sandisk’s own Sandisk Imagemate (SDDR-189-A20) and also my laptop (Dell Vostro V13) own SD Card reader, both producing identical results! 

The format was the default (came from factory). Anything I’m missing here?

I have that same card and we have the same benchmark test. That extreme pro card already has the new UHS technology. Host device would need to handshake with the uhs tehcnology to achive its lightning speed. The d7000 and 60D are the only camera that i know which takes advantage of the uhs speed.
