    Hi there,

    I just got my iMac Late 2015 and according to this blog post the iMac should have NVMe. I checked my iMac and it does not contain any NVMe. I have the 1TB SSD and the model is APPLE SSD SM1024G. Does anyone have any experience in this?

    I have a 1tb SSD in my iMac (APPLE SSD SM1024G) which is brand new as well.

    Mine is reporting the following under NVMExpress in System Info:
    This computer doesn't contain any NVMExpress devices. If you installed NVMExpress devices, make sure they are connected properly and powered on.

    My speeds are sick though, 1500 MB/s write, 1824 MB/s. I don't see another Apple NVMe drive on this list above ours.

    Mine also doesn't show any NVMExpress devices, but maybe that's because its "fused" together. I have a 2TB Fusion drive and like swamyg1, its wicked fast.

    Interesting. Maybe only the 24GB SSD has NVMExpress. Can someone confirm?

    To use a Fusion Drive, the Mac needs to be able to talk to the PCIe SSD and the SATA hard drive. Since NVMe only works with PCIe and isn't compatible with SATA, this probably means Fusion Drives can't use it.

    I have a 512 Flash drive and it too doesn't report as NVME and as an SSD. However, run Blackmagic Speed test and you'll see you get speeds far, far in excess of a standard SSD. So it's an operating system reporting thing, not a reality.
