This is the very old debate for the intel SATAII vs marvell SATAIII.
I recommend to intel, because it will run more stable. From the benchmark, the marvell maybe little bit better than the intel, ( * In the old time, intel was better than the marvell. Now I don't look for that info, marvell maybe update the firmware so that the performance may get better), but you want to run the PC more stable, also you will not notice the difference in the real-world.
