I ordered a Samsung 840 evo 250Gb, i actually wanted to get 500 Gb but that was too expensive, because i realy need a good new headset too (Steelseries Siberia V2), my laptop actualy has 2x2,5'' S-ATA rev. III and 1xmsata, 1xSATA Rev.I (for dvd drive), so i can just
add a SSD to the msata slot if i need more, the crucial msata 250Gb just costs ~100 Euro so that would an option later
