Samsung 950 performance on PCIe 2.0 x4

[westleyd]

I'm planning on putting a Samsung 950 m.2 NVME SSd into my old X58 system using a straight through adapter card.

I know that that Samsung 950 is a m.2 PCIe 3.0 x4 device and that my PCIe X58 (Gigabyte Guerrilla G1) is PCI 2.0 (Gen2). Therefore the Samsung 950 will be operating on x4 (4 lanes) but will be Gen 2 (PCIe 2.0)

Does anyone have any real world performance results of the Samsung 950 running on PCIe 2.0 x4?

It won't work on x58 based systems. The functionality needs to be added with a bios update and considering the age of the platform, its not going to happen.

Hi there, just clarify it will work on X58. It will work and primarily operate as a straight NVMe storage device, utilizing the Samsung driver for Windows. It will not function as a bootable device as UEFI BIOSis required for booting. And X58 chipset doesn't have UEFI BIOS. So it definately will work on X58 as a storage device.

Here is one example of the Samsung 950 being used in a X58 system. https://www.youtube.com/watch?v=L6kZO_r0hco

So back to the OP I just wanted to get a handle on real world performance levels whilst operating on a PCI 2.0 x4 slot versus PCI 3.0 x4. At the moment all I have to go by is the video referenced above.

Thanks for any relevant input.
