AnandTech Storage Bench - Light

Our Light storage test has relatively more sequential accesses and lower queue depths than The Destroyer or the Heavy test, and it's by far the shortest test overall. It's based largely on applications that aren't highly dependent on storage performance, so this is a test more of application launch times and file load times. This test can be seen as the sum of all the little delays in daily usage, but with the idle times trimmed to 25ms it takes less than half an hour to run. Details of the Light test can be found here.

AnandTech Storage Bench - Light (Data Rate)

Once again, Samsung breaks its own unchallenged record with average data rates on the Light test. The NVMe drives all show a relatively large disparity in performance when the test is run on a full drive compared to starting on an empty drive, while the faster SATA drives have very little room to perform better on an empty drive.

AnandTech Storage Bench - Light (Latency)

The 960 Pro shows almost no improvement in average service time, but it doesn't need to since its worst-case full drive performance is better than the competition's best case.

AnandTech Storage Bench - Light (Latency)

Of the PCIe SSDs only the OCZ RD400 experiences more than a handful of operations that take longer than 10ms to complete. The Samsung 850 EVO is itself an odd outlier because the Light test fits entirely within its SLC cache, so no operations take more than 10ms.

AnandTech Storage Bench - Light (Power)

The 960 Pro's power efficiency is once again similar to the 950 Pro: better than the other PCIe SSDs but not as good as a decent SATA SSD.

    The Intel 600p is very high on my to-do list. Since it's also using the Microsoft NVMe driver I want to run it through some more tests before publishing the review, but it should be done before I get the 960 EVO.

    Curious about the operating temperatures of the drive, Im guessing that Destroyer gave it a good thermal workout :) Puget Systems have done some testing on the effect of adding cooling to M2 SSDs:
    https://www.pugetsystems.com/labs/articles/Samsung...
    Aquacomputer also make a PCIe Riser card equipped waterblock for M2 drives for those who want to water cool their SSD, the kryoM.2

    Does anyone know if moving an M2 drive to a riser card improves cooling for the drive? I would think there is a little bit of improvement bringing the drive off the surface of the motherboard... How if at all is everyone keeping their motherboard mounted SSDs cool?

    @WatcherCK

    Yes, moving an M.2 drive to a riser card improves cooling (at least in my system). I checked temperatures mounted on my motherboard with a spot cooler directly on the 950Pro. I then compared it against mounting on a Silverstone ECM20 and an Asus Hyper M.2 X4 Mini (no spot cooler). If you are able to direct good airflow to the riser card, as I was, the Asus riser card is significantly cooler even though it had no spot cooler. If you use a thermal pad on the back of the M.2 drive on the Silverstone EMC20, it may in fact do even better than the Asus, but it my system, the larger standoffs allowed more air to flow behind the M.2 drive on the Asus solution. In any case, I can't seem to induce thermal throttling on my 950Pro in my setup regardless of how hard I try. Again, it will depend on how much airflow you can deliver it.

    Those SSDs suffering from HEAT. If you don't put a forced cooling on them, it will DEGRADE the speed no matter what! This is why you won't see much than 3GB/s !

    Where are these performance heading. Where Do we need to go. The destroyers and heavy definitely dont represent 95% of the consumer users usage. Do we need more higher Random Q1 Read Write? Or do we need higher Seq Read Write? If so then we dont need our firmware and powerful CPU core for QD32. Will that save cost? Why are we still within the 5W power usage? When can we get those dropped down to 2W or less.

    blazing fast. i will not be able to make useod this speed except for W10 upgrades

    @ Billy Talis: Would it be possible to test on another mainboard? There seems to be a clear bandwidth issue for sequential transfers, as other tech sites as https://www.computerbase.de/2016-10/samsung-ssd-96... achieved almost 3400 MB/s in CrystalDiskMark for the 512 GB model. At first they struggled to reach more than 3100 MB/s. (Samsung values were achieved with CrystalDiskMark according to computerbase).

    How is new dies and an entirely new controller 'just a generational refresh of the 950 Pro', from any angle?

    The Samsung 2.1 driver has DPC latency issues on my end. I am usign a Samsung 960 500GB Evo nvme and using it with the Native Microsoft Driver (Windows 10 with latest updates installed) or the Samsung 2.0 driver, all is ok, DPC latency reports are fine - Latencymon and latency checker both report trouble free operation. However, installing the 2.1 driver, both Latencymon and dpc latency checker report problems with storport.sys and problems with DPC. Rolling back the driver from the Samsung 2.1 to the Microsoft or the Samsung 2.0, all goes back to normal
