Well i am about to buy a Corsair Force GT 240gb SSD that i intend to use as OS / most used programs and games on.
I really need to make a upgrade since my 4 years old western digital is getting slower by every passing day.
I chose Corsair since i trust their quality and support in general, Got PSU, 650 Case, 16GB ram and many other things from them already.
OCZ Vertex 4 and Samsung 830 are both newer and better drives which cost ~$190 (256 GB). If you can get the Force GT for significantly less, go for it.
