    Hi all,

    I'm trying to find out if a change in SSD from my Sonnet Tempo SSD setup (stripped in RAID0) to a blade SSD will give a time saving, noticeable increase or if there is a limit to what is actually noticeable with regards to random read writes, or sustained large file import exports.

    The Sonnet Tempo PCIe RAID0 config is giving read writes of the following:

    I am also running Windows 10 with a single SSD on a Velocity Solo X2 PCIe card which gives these results:

    All SSD's mentioned are Samsung 850 evo's.

    What I would like to know from users experiences when dealing with video editing (upto 4K - most 1440) in DaVinci resolve (In Yosemite on RAID0 SSD), FCPX, Autodesk products, is will I see a noticeable time saving from exporting/importing/working within the software from the SSD RAID0 to something like a M.2 SM951 on a Lycom DT-120 PCIe adapter?

    Rig:

    4.1-5.1 12c 3.46ghz x5690
    48gb Ram
    8TB HDD
    2x250GB 850 Evo's PCIe Sonnet Tempo RAID0 - Yosemite
    1x500GB 850 Evo PCIe Velocity Solo X2 - Win10
    GTX Titan (with internal PSU)
    BluRay Burner
    DaVinci Resolve
    FCPX
    Autodesk Fusion/AutoCAD/

    Thanks in advance.

    The bottom half of that benchmarking app is more important than the top half. The top tells you very little about real world use. You will see improvement if you're handling multiple 4K files if they have a very high bit rate but don't expect the world because at the end of the day all that data has to go through your CPU and the software itself has its limits.

    OK... thanks for the reply, so you would expect to see an advantage when adjusting, importing, exporting 4k video files but the limitation then becomes the software so if for example DaVinci is rendering at 30fps on a 4k video, the limit is with the cpu and gpu and software not that its bottle necked by the speed of writing the file to its saved location? I could probably work that out by monitoring the SSD write speed during this process but just interested to find out other peoples views. I know blade SSD's are relatively cheap now so this might be worth while for my work process.

    You would only benefit in pure write operations. Export from a graded resolve timeline is usually around 30fps with a Titan so there's no benefit there.

    I have a similar spec machine. Mac Pro with Titan X, 96gb ram, 12 core 3.5ghz, 4x striped 850 evos... But I've noticed in resolve 12 I get better ui responsiveness on my retina iMac. I think the single core and bus speeds still have a lot of impact...

    The performance of an SSD drive can't be measured by simply looking at BlackMagic's speedtest. Try reading an SSD review from Anandtech for example (the reviews for the SM951 and Intel 750 are interesting in that matter), there are many variables at stake (bandwidth, IOPS, latency, workflow...). As for how does it translates in terms of real world performance well... I can only trust the reviews as I haven't tried one of these myself. Some say it does, some say it doesn't.
    Yeah, that would be wise. I'm sorry I don't have such experience to give you.

    REALLY? better UI on the iMac... even with the Titan X? I have the original Titan OC which is ok but was thinking of another upgrade session of blade SSD's and a Titan X but from what you say it appears (at least in my work flow also resolve 12) I will not notice a big impact :(. Guess I am just trying to remove bottlenecks where i can, the 850 Evos are ok they do the job just interested to hear real world feedback from users like yourself that use similar software.

    Thanks :)

    Ok that for the feedback, I am aware that BlackMagic speedtest don't show the whole picture, they are just a quick tool to put a line in the sand so to speak. thanks
