Faster than expected!

My Macbook Unibody aluminum has been over time a little slow, whatever it was that my hard drive never had more than 10GB free, rather only 2 GB.
I pondered until I buy the 1TB WD Scorpio Blue, but as it comes to me on speed because I've resorted to Black and see - even without Clean Install of Mac OSX, the Macbook is running the same much faster, simply TimeMachine taken Backup and you get the feeling of the computer comes fresh out of the store, because of the greater capacity, which allows the computer to work better, and the read / write speed is impressive. Programs start felt twice as fast as before and the noise has only increased minimally if at all - access is perceiving not large, only the noise has become a little bit louder, but not at all disturbing. And even if the board needs more power, I think that the Geschwindikgeit the loose irons out again.
Even the delivery went very fast, even on Good Friday was sent out!
Buy as long as it is still available ;-)
