it remains the SSD (low end as dis) But my WIN7 starts at 1/4 turn! I count the dice 23seconde presses on / off my lap software loading are very fast, and the transfer rates are friendly but I do not know how many MB / s for now. Anyway for the price does not take 7200 / min classical (that is clearly slower) A remake, I'd take a single 120 GB to install the OS enough and another for banks of sample (music) In short it is very good, but still to see the result in 5 years if the SSD is still alive ...
