Samsung 970 Evo Plus nVMe Question

Devastator0 · Dec 25, 2019

Hopefully this will be an easily answered question but I just built a new system with a 1TB Samsung 970 Evo Plus nVMe as its boot drive. Once I had Windows in it and installed the Samsung nVMe driver on, I installed a 2nd nVMe of the same type into the system. In Windows Device Manager & in Task Manager, the first drive correctly shows up as a “Samsung 970 Evo Plus 1TB” but the 2nd drive shows up as a “Samsung 970 1TB nVMe SCSI”. Any idea why that would be the case?

Probably the second drive still runs on stock Microsoft NVMe driver.
Select View -> devices by connection in device manager and notice how the NVMe controllers are named under which the drives appear.

I tried this but I couldn’t see the drives. Or the nVMe controllers listed. When I am looking at Device Manager normally I can see 2 Samsung nvme controllers, but not under the view you mention.

They are there - but you have to dig deep

Or simply select the disk with "by type" view, and then switch the view to "by connection" - you'll see where it exactly is (assuming you have win8+).

You are right, I’m blind lol. Ok, so the first drive is listed under “Intel PCIe Express Root Port #9 - A330” & the 2nd, incorrectly named one, shows up under “Intel PCIe Express Root Port #21 - A32C”. Both are then under a subheading for the Samsung nvme controller.

You can try manually updating the driver of the SCSI one to the Samsung driver.

Might just be the way the controller for that particular M2 slot on the motherboard identifies itself.

Yeah good point, I’ll give that a crack.

Yeah I already have it installed.

Hmmm I was thinking that may be the case.

If it's working fine no need to change anything, IIRC the difference between MS' latest (NVMe) drivers & any other manufacturer driver is minuscule.

Try running Crystal Disk Mark or AS SSD benchmark and if the "SCSI" drive is substantially slower than the other one, then worry about it, otherwise ignore it.

Well I am just using the microsoft driver and my read/writes are great.

Is there something else that should be better with the samsung driver?

So, as an ending to this, I swapped the drives around between the 2 nVMe slots on the board and now the initial drive has been picked up as the SCSI device. It would the. Just appear that the board’s (a ASUS Maximus XI Hero WiFi) 2nd (I.E. Lower) M.2 slot reads the drives in a different manner than the upper slot.

Regardless, I’ve run some benchmarks and both drives are within a few mb/s of each other. Reads are ~3530ish MB/s and Writes are ~3245ish MB/s.

Cheers to everyone who has commented! Much appreciated.

Edit: Also, if it matters to anyone who is anal about such things, the bottom slot is considered the “Primary” slot by the Windows 10 installer. It sees the drive in that slot as Drive 0. Again, just if it matters to anyone.

Edit 2: It gets a bit weirder, so I just did a Windows 10 reinstall and both drives are now detected as “Samsung SSD 970 EVO Plus 1TB”. Forgive the language, but I’m fucking stumped now lol
