    A very interesting situation with the g751jy and the samsung sm951 pcie ssd

    an interesting situation to report on, concerning my g751jy and the sm951 pcie 512gb ssd. while my samsung sm951 benchmarked on crystaldiskmark 4 with 1600mb/s seq read, and 1458mb/s seq write, when i retried a
    suggested test from an earlier post, i got an interesting set of numbers.

    the test was to transfer 20gb's of vid from one partition to another. so while i did this, the transfer box in
    windows 10 shows the speed of the transfer as it goes, and mine showed 1.8gb/s and did it in just over 11 seconds. the rate fell slightly as the transfer continued, but for the first half of the transfer, it was a solid 1.8gb/s rate, and only fell off at around 65 - 70% finished, down to around 1.5 - 1.3gb/s. that's blazing fast for a large video file. so now i am wondering if anyone else has played around with actually timing and testing any other functions of this drive? i would be very interested to know their results. i am using windows 10 build 10240, on my G751JY, with a Samsung sm951 AHCI, pcie 3 512gb drive in the same bay as my 1TB Samsung EVO 840. and temps maxed out at 53c during the process. and even though i have them in the same bay with only a piece of electrical tape between them, the sm951 idles at 32c, and the 840 EVO idles at 33c. i've rarely seen either drive get above 56c.

    UPDATE: i have done the test over and over, first from one partition on the sm951 to another one on the same drive; both partitions are system partitions. then i performed it going from a partition on the sm951 to a partition on the 840 EVO. with each test, i both copied and then moved the video files, and changed the giver and receiver each time. the cool thing was on a couple of occasions, it started out over 2.0gb/s, but at those times where it did, it also fell more drastically at the end below a gb/s, down to as low as 800 or 700 mb/s. but no matter how high it started or finished, it always seem to time around 11 seconds, being a little faster than that on some occasions, and a little bit slower than that on others. but it was always within a second.
