Meanwhile, I have the Samsung SSD 830 128 installed in two devices as a system disk. On the one hand in my PC (there she has an OCZ Vertex 2 SSD displaced, reached only half the speed and otherwise made only problems that has) and on the other hand in my laptop (Samsung RC530S0B - BJ end of 2011). The performance gain is enormous, especially in the laptop. There was a slow HDD installed that has formed the bottleneck. Despite fast processor, opening programs lasted an eternity. Now with the SSD It feels like when you have a new laptop in hands (even though it is only as three months). I have chosen deliberately for the Samsung 830 128 and against the 750 GB internal drive, although I now have some households with the place. But here the performance gain was happening clearly. The internal HDD I plugged in a USB enclosure and can now take advantage of this if necessary.
Like many users I have re-loaded onto two Windows systems to have a "fresh" system.
I am more than satisfied. Strong buy recommendation!
