Got the 850 Pro 128GB on sale for $88.00 with free shipping. Couldn't resist but I have to wonder how valid the 10 year warranty really is. I only spoke to Samsung Tech once, but they were very nice and polite. I also have the 840 EVO and the 840 Pro as well and they are all so fast that I can't tell one iota of difference between the bunch in the real world. Yes, my 850 pro is faster in benchmarks but that's about it.
