PCMark Vantage HDD Tests

PCMark Vantage is an objective hardware performance benchmark tool for Windows computer systems. The HDD test inside PCMark Vantage is well suited for testing all types of connected storage devices. Benchmark Reviews has decided to use the HDD Test Suite to demonstrate simulated real-world application performance on the drive. PCMark Vantage runs eight different storage benchmarks, each with a specific purpose. Once testing is complete, results are given a PCMark score while and detailed results indicate actual transaction speeds.

The 512GB Samsung SSD 950 PRO produced a total PCMark Vantage (secondary) HDD Test Suite score of 211,873 on the X99 platform, while the Z170 system scored 210,264 PCMarks.

    Hi. Why u used the adapter for the x99 deluxe and not the integrated M.2 Socket?
    I buught one of those but i couldn’t make it works on my x99 deluxe.

    It is not compatible with the M.2 X4 socket?

      Looking at their website, it doesn’t appear that the ASUS X99-DELUXE has an integrated M.2 socket. See for yourself: https://www.asus.com/us/Motherboards/X99DELUXE/

        The x99 Deluxe very much does have an integrated m.2 socket, and it even ships with a secondary extended pci-e x4 m.2 bracket.

        I’m having the same issue of it not being recognized in the BIOS, but the device seems to be recognized in Windows (running Windows 10).

          Did you ever get the 950 pro to appear in your bios. I have the similar problem with the X99 Deluxe (1st edition).. Also nothing appears under NVME in the bios. Does boot into windows 10.

          The intel 750 series NVME does appear in both the boot section as well as the NVME section although the latter has no configurable settings.

    Why does Crystalmark show such low 4K read speeds vs some of the other benchmarks? I have the 950 pro installed on a z170 Asus Hero VIII and I have that same issue. In fact, Samsung’s magician also reports about 208K with 4K IOPS read.

      That is an excellent question, and the only answer I have is “I dunno.”

      Hard disk drive performance is extremely repeatable: the platters have defined sectors, the drive may have a few megabytes of cache, but in general I can run various read and write tests all day long and see very little variance in the results.

      SSDs are something else entirely. They’re little “storage computers”, with multi-core processors, varying amounts of cache, and different strategies and internal protocols striving to balance performance with NAND durability. When I send a command to a hard disk, about all the controller does after a cache check is figure out which platter, track, and sector I want to deal with; when I send a command to an SSD, well, who knows what’s going on? It’s an evolving system and the various vendors don’t disclose the operational details for competitive reasons. Samsung doesn’t publish any details on the “UBX” controller they use on this drive, so all I can do is speculate.

      What this boils down to is:

      A. Running the same test multiple times can yield different results. Simple example: run a linear write test on a “clean” SSD, followed immediately by another run of the same test. The second iteration will show significantly reduced performance since the controller will have to erase each “sector” before writing to it the second time.

      B. Performance during a test can vary. Look at the AIDA64 linear read test on the Z170 and X99 platforms. Why are the results “smoother” on the X99? Again, who knows?

      Complicating the issue is the fact that this is our first NVMe SSD. Is this a factor? Will all NVMe SSDs show this relative to AHCI SSDs? Stay tuned! In the meantime all we can do is run the tests and report the results.
