Samsung 990 Pro NVMe on Dell Ultra 4x M.2 NVMe SSDs to x16 PCIe Adapter Card 80G5N 6N9RH TX9JH DPWC400

Hello Everyone,

As the title states, has anyone here tested the latest Samsung 990 Pro NVMe on Dell Ultra 4x M.2 NVMe SSDs to x16 PCIe Adapter Card?

Part Numbers: 80G5N 6N9RH TX9JH DPWC400

As per Dell's official website,

  • Dell Ultra-Speed Drive card is a multi-port M.2 PCIe interposer card that converts PCIe to M.2 (NGFF) to support NVMe SSD*

Since Samsung's 990 Pro NVMe's are not NGFF.

Hello, I'm just adding this to clarify the card is for workstations, not servers.

Re:  Since Samsung's 990 Pro NVMe's are not NGFF.

Samsung 990 Pro NVMe SSD with M.2 form factor =  NGFF (next generation form factor)

For this topic query, Yes, the Samsung 990 Pro NVMe SSD will work with Dell Ultra-Speed adapter.

Note:  For multiple drives to work, the adapter must be installed on PCIe x8 slot (x2 drives) or PCIe x16 slot (x4 drives) on selected systems with motherboard that supports bifurcation.

Hello @DELL-Young E​ 

I appreciate your clarification, but my query was not about whether the card would run/support servers.

I already had the chance to look at the SS you shared.

I specifically asked whether the latest Samsung 990 Pro NVMe would run/support the card and has anyone tried/tested yet because as per my findings, I haven't found any literature or video on the internet that someone has tested/run those latest NVMe's on the card.

Furthermore, I would like to seek more clarification from you on the card/adapter:

Since, regarding your SS shared the card is built to work on Workstations and not servers, does that mean it will not work on an x16 PCIe slot on a Dell R740xd server? I mean would it not get detected on the server? or would it get detected but with limited connectivity?

I understand that you're trying to explain that the card was not built for servers but only for workstations but if we still plug it in on a R740xd x16 PCIe slot, would it work on its 100% capacity and functionality? or would we have any kind of challenges/limitations?

Yet, my question still stands there whether the card would support 4x Samsung 990 Pro 2TB NVMe's?

Hi @Chino de Oro​ 

Thanks for the reply and clarification.

I had the same understanding as well but I got a little shaky after I found the following from ChatGPT 4o:

Is Samsung 990 pro NVMe NGFF?
ChatGPT said:
ChatGPT

No, the Samsung 990 Pro NVMe SSD is not an NGFF (Next Generation Form Factor) SSD. It is an M.2 NVMe SSD.

Here’s the distinction:

Samsung 990 Pro

  • Interface: NVMe (Non-Volatile Memory Express), which is a protocol for SSDs connected via PCIe.
  • Form Factor: M.2 (2280), where 2280 refers to 22mm width and 80mm length.
  • Connection: Uses an M-keyed connector to fit into M.2 slots on modern motherboards or devices.

NGFF

  • NGFF, or Next Generation Form Factor, is an older term used to describe the M.2 standard when it was first introduced. While NGFF can technically describe M.2 drives, the term is rarely used today, as "M.2" has become the industry standard terminology.

So, while the Samsung 990 Pro is physically an M.2 SSD, it would not typically be referred to as "NGFF" in modern documentation. It is more accurately described as an M.2 NVMe SSD.




However; 


80G5N support Samsung 990 pro nvme?
ChatGPT said:
ChatGPT

Yes, the Dell PCIe x16 NVMe Adapter (part number 80G5N) should support the Samsung 990 Pro NVMe SSD, provided that the following conditions are met:

Key Compatibility Factors:

  1. Form Factor:

    • The Samsung 990 Pro is an M.2 2280 NVMe SSD, which fits the M.2 slots on the 80G5N card. The 80G5N is designed to host up to four M.2 NVMe SSDs.

  2. Interface:

    • The 80G5N supports NVMe PCIe SSDs, and the Samsung 990 Pro uses the PCIe Gen 4 interface. Even if the 80G5N does not support full Gen 4 speeds (depending on your system’s PCIe version), the drive will still function at Gen 3 speeds.

  3. BIOS and Bifurcation:

    • Ensure the server or workstation where you install the 80G5N adapter supports PCIe bifurcation, as the card splits a single x16 PCIe slot into four x4 connections, one for each M.2 SSD.
    • The Dell PowerEdge R740xd, for example, supports bifurcation (configurable in the BIOS), making it compatible with this setup.

  4. Thermal Considerations:

    • The Samsung 990 Pro is a high-performance SSD, so ensure proper cooling in your system to avoid thermal throttling. The 80G5N does not come with individual heatsinks for the drives, so you might need to add third-party M.2 heatsinks if necessary.

Final Recommendation:

If your system supports PCIe bifurcation and the 80G5N card is properly installed in a compatible PCIe x16 slot, the Samsung 990 Pro will work perfectly. Just keep in mind that its performance will depend on whether the system supports PCIe Gen 4 (for full speeds) or runs at PCIe Gen 3.

As you can see, the lengthy AI answer is basically the same as mine two sentences.  The adapter supports Samsung 990 Pro SSD.

About NGFF, there is a term GIGO that may explain why AIs will provide different answers at time.  I looked up on Google and received the AI answer as below.
