I am looking for a good 120gb or 256gb SSD to use as a boot drive for my Gaming PC, to be paired with an HDD. There is a MicroCenter by my house so that will be where I am buying the SSD. I've heard that basically the Samsung 840/850's are the best bet, but can I get anything cheaper for around the same performance? I've heard about some SSD's having bad V-NANDs or something like that, so that is why I ask.
