Accepted Answer

I can't link Westerndigital website spec comparison chart.
But based on the spec comparison sheet from Western Digitial, seems the WD3003FZEX ( 168 MB/s )is faster drive than the WD3001FAEX ( 154 MB/s ).  Also the WD3003FZEX has Advanced Format capabilities.  You can search Wikipedia for more info on what Advanced Format is
