ASRock Z87 Extreme11/ac Mobo Reaches 6 GB/s & 850K IOPS


The AS SSD Copy Benchmark is probably the closest ‘true to life’ test available in any of the synthetic benchmark tests available today.  It simply takes three different files, an .ISO, a program and a game and moves these from one part of the SSD to another, monitoring the time taken to transfer and maximum transfer speed reached.  For our purposes today, our charts will reflect first the time taken for the transfer, and then the maximum transfer speed.  As well, RAID and single SSD testing will be combined.


AS SSD Copy Benchmark Times

Looking at the top speeds, it just doesn’t get better than transferring a file in less than a second.  We will elaborate on this a bit later with some actual file transfers of a large volume.

AS SSD Copy Benchmark Speeds

Much the same can be said here when we are transferring at 1.8GB/s.  That is the equivalent two 2.5 HD movies a second.


For this test, we used a 25.5GB file consisting of 1x Blu-ray movie, 3x 3D HD movies and 8xHD movies, and transferred the folder from one part of the logical drive to another.

Movie File Transfer

As much as you have to truly appreciate moving 25.5GB of files in less than a second, even the transfer speed of 1min 16 seconds from a single drive is amazing.  Great performance!

    We threw 25.5GB of mixed movie files at the RAID0x8 configuration and it moved them from one place to another in 22 seconds, less than a GB per second.

    Do you mean more than a GB per second ?
    Whatever it is some speed. What does one of these beasts cost?

    How come you didnt run a Vantage?

    • blank

      We did run Vantage at all levels but there was no appreciable difference from our first result of 61124. The marks were 67724 (X2), 68851 (X4) and 68820 (X8). We felt including this served no purpose as Vantage feeds on new SSDs best, whereas these were definitely not anywhere new, and also, these are enterprise SSDs. Our main purpose in testing was seeing how high of an output we could reach from the motherboard.

    cant really find an answer, is it possible just to make a 16 ssd raid 0 using these 16 slots? is this what you are going to test next? i am asking because it is mentioned up to 10 drives can be used in raid in asrock website.

    • blank

      Yes… Just because it’s an effective answer for much that we do but the truth is that we wanted to see how high we could get with ad many SSDS as possible to go along with an amazing build.

    Can not wait for the 16x SSD review!

    Currently using the LSI SAS 9300-8i with 8x SSDs.

    were you able to get the 12 SSD’s connected and tested? Is that still forthcoming or did I miss it somewhere?

  6. blank

    if you use all the ports on the LSI controller and run 4 way GPU, what will the PCI-e config will be ?

  7. blank

    Is there any way to flash the LSI controller to allow raid 6?
