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

ATTO DISK BENCHMARK VER. 2.46

ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

The low RAID0 x8 performance of the Ultrastars was a bit concerning at first as we figured our testing would easily exceed 4GB/s and ATTO uses highly compressible data.

CRYSTAL DISK BENCHMARK VER. 3.0 X64

Crystal Disk Benchmark is used to measure read and write performance through sampling of highly compressible data (oFill/1Fill), or random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.

Once again, we weren’t very happy with the performance we were seeing from our typical consumer SSD synthetic benchmarks, although it was refreshing to see the low 4K random write performance increase

AS SSD BENCHMARK VER 1.6

Up until recently, AS SSD was the only benchmark created specifically for SSD testing and it uses incompressible data.  AS SSD, for the most part, gives us the ‘worst case scenario’ in SSD transfer speeds because of its use of incompressible data and many enthusiasts like to AS SSD for their needs.

    Hi,

    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.

      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?

    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?
