I have been thinking about getting an ssd for my system. I would solely be using it for win 7 and frequently used programs. I was thinking that I would get an 840 evo but today I said newegg has a corsair ls 120gb ssd for $45 AR. Currently the 840 evo is $80 for the 120gb model. Would there be any significant reason I should choose the evo over the corsair ssd for what I am intending to use it for?
