Power Consumption

To quantify power consumption we're looking at total system power, which takes into account the CPU load associated with workload generation as well as the power drawn by the drive itself. The P3700 was left in its default lower power operating mode, not the higher 25W mode.

Overall the P3700 doesn't raise any power consumption flags. The overall system power consumption ends up being around 16W higher than with a single S3700, but if you normalize for performance the two end up looking quite similar. There seems to be some power savings compared to the old Intel SSD 910, and roughly comparable power consumption to the P420m.

    The Revodrive 3 presents itself as a SAS device as I understand it. In any case the problem isn't that the board can't see the drive period - the ASRock system browser cheerfully identifies it as an Intel drive - it just doesn't consider it bootable. This is with the latest BIOS (3.10) BTW.

    To answer your second question, none of the other PCIe drives we have are bootable. The Intel 910 is explicitly non-bootable, and the Micron P420m uses a proprietary protocol.

    just found a gerat piece of information - maybe you only need the right driver (or windows version where this is included out of the box)
    "NVM Express Boot Support added to Windows 8.1 and Windows Server 2012 R2"
    details:

    hopefully this works for these devices...

    Thanks for the article. I'm glad the new interface is showing good results so far. People are probably drooling for the new storage hardware options coming eventually. Reply

    I personally would like to see results in a dedicated gaming rig. Reply

    I think that gaming performance is the least of your concerns with this speed monster. Reply

    Minimal loading times and no I/O-related hitching still sounds wonderful though. Reply

    Excellent QD1 performance is what matters for a workstation or enthusiast machine, so this is EXTREMELY promising. Reply

    I would like to see what this could do on an ESXi host running Pernix Data's FVP. If supported, these cards could make that solution much more affordable from a hardware perspective. Reply

    are these types of drives only going to be on PCIe.. or are sata-express drives planned as well ?? depending on ones usage... finding a PCIe slot to put a drive like this in.. may not be possible, specially in SLI/Crossfire... add the possibility of a sound card or raid card.. Reply
