I'm looking for a reliable SSD to last a good time without slowing down speed like my old SSD did, its speed decreased by 50 mb/s in read and 30 mb/s in write, it also had rubbish write speeds to begin with. I'm looking at the Samsung 840 pro 128gb since it is MLC ( lasts 3 times as long as TLC) and is fast to boot, but it's on the expensive side. I'm willing to fork out a little more for a much better drive so I need suggestions.
