I've got the 950 Pro mounted in an Asus M.2 PCIe adaptor from day one and have been using it as my OS drive in an ASUS Z97M- Plus mobo with an i7-4790 cpu, 16 GB of ram. It's been in use about 2 years now and no hardware changes to the system since i built the PC.
Original benchmarking with samsung's magician showed sammy's advertised specs -2550 MB/s read & 1500 MB/s write speeds. Other performance utilities, namely AS SSD, ATTO Benchmark & Anvil Benchmark also supported or confirmed Samsung's magician's samplings.
Then i started to notice a downward trend - this afternoon read speed had dropped to 1540 MB/s and write speed to 876 MB/s, so read speed is down 40% and write speed slightly more.
Heat is not an issue as i've had a small 40MMx20mm fan mounted directly above the controller on the SSD, and temps are monitored with Hard Disk Sentinel - have never seen the disk temp go above 57C
Samsung magician also reports the drive is in "good" health and shows 5.1 TB have been written to it.
Are others experiencing that kind of performance drop?
