The laptop it's going in has a m.2 data see now(256gb), just wanting some more room. The Its a high end business latitude i7-7820HQ (4c/8t), w 32gb 2400 ram. It's pretty fast/quick as it is, I don't do many large file transfers, <1gb between laptop and servers. The 860 would not be slow at that at all, but it I can get nvme for $35 less at the 1TB size, kind of silly not too. As usual everyone has given much to ponder.
Trust me with the firmware update and Rapid storage program for the 660P but mostly price. There is an argument for the 660P being the best value in storage for any platform. I rememebr when traditional SSDs were first launched there was the argument about durability when we went from SLC to MLC. Now the argument is about QLC but I can tell you the Intel is faster, in every regard than my Sandisk Ultra 2 960GB and my Micron 11002TB SSD.
