OS X Driver for NVMe M.2 Solid State Drives Released

Adding the Kext in the clover EFI partition i could boot up from the INTEL 750 SSD! : ) The only problem now is the PCI Link speed is limiting the speed of the card. x4 whilst it is x16 Any ideas anybody how to change that?

Sounds great!! Thanks!

The card actually is a PCIe x4 card, so you should be getting full speeds. x16 wouldn't change a thing.

It maxes out at 400 write and 370mb/sec read which is weird as it should be able to do 4 times more, at least in windows it does. But maybe this is a driver issue.

You're right, it should be hitting four times that speed. That's odd.

My bet is that the driver is holding it back.

Intel's 750 ssd is only 4x PCIe so that sounds like it is operating normally.

True but the Speed is at 400MB per sec which is very slow for the device.

I have an UD5 X79 - not sure bios can see it. Think I need a newer logic board.

X79 MB dont have NVME support in BIOS. It still should work in Clover as a fast data drive

I am getting about 1035 read and 843 write on the Intel 750 PCIE3 X4 SSD. The write seems on spec with a max of 900MBps. The 1035 read speed seems half as good as it should be. But I'm not really complaining, as this Intel SSD is still plenty faster than my former Mushkin SSD's in a RAID0 array (and half as simple to install).

The SSD is in PCIE X8 slot, while my Nvidia GTX 760 card is in the PCIE X16 slot.
