I might have missed the sarcasm in that post, but the results are annoying (my similar spec is about to be delivered). 700MB/s is nothing to sneeze at, but since they can get the rMBP and nMP with 1Tb SSD to hit 1000 and more, it feels a bit mean of them to have put a comparatively crippled SSD in there...
Apparently Apple sacrificed some "lanes" for more external USB ports. You can't have everything.
