I also might add.......installing a good SSD (and the Samsung is the best), is the absolute best way to add speed/performance to your system. When I say your head will spin, I mean it. I couldn't believe the performance that an SSD gives. 99.9% of the time, your performance "bottleneck" is in the I/O. An SSD is without question the best way to get more out of your machine. You won't be sorry you did it.
