PCIe Slot Splitting in 5810?
Hi all, I'm looking to replace my spinning 1TB disk with 2x 1TB NVMe sticks i have accumulated from past laptops, and put it into my Precision 5810 to use purely for storage. I was planning on setting them up as RAID 0 with software RAID. I found a card on ebay that referenced something called PCIe bifurcation or splitting, and they said to make sure my motherboard supported x4x4x4x4 on my x16 slot. Here's a link to the one i'm looking at: https://www.ebay.com/itm/402804244824. As i look in my tower (i'm going form the bottom up as in this listing: https://qrl.dell.com/Files/en-us/Html/Manuals/T5810/Avalon3SystemBoardComponents=GUID-B80A46A7-753E-49FB-82F6-474D3A37BBA6=1=en-us=.html), i currently have PCI slot 1 for my sound card, PCIe slot 2 and 3 are free, slot 4 is covered by my graphics card in slot 5, and PCIe slot 6 has my NIC in it. I had read in other posts that the 5810 should work with these types of cards, but i wanted to verify which slot i should plug it into. I'm guessing my remaining PCIe 3.0 x16 slot would be perfect, but i hate that it's so close to the GPU, I would prefer it to be in this one: PCIe x16 slot (PCIe 2.0 wired as x4) though it doesn't sound like that would work properly.
Am i right or wrong in my thinking? Any advice or thoughts would be appreciated. Thanks!

@the.mknabster , yes, that is a dual slot Dell OEM. I like that version better than the Quad Ultra Speed Drive because beside good cooling, it does support the enterprise NVME (the long version 110mm). Asus Hyper stock would be in and out, but Amazon warehouse in US had them on special around 40 USD, so keep an eye out for them. Also check out the Cablecc dual and quad and they had been around 25 to 30 USD, and they have good review on US Amazon.

Thanks for your response Chino! Especially with it so close to the GPU, i do worry about overheating with them. Have you ever heard of the Dell DPWC300 card before? I found one on ebay for a reasonable price and it has a fan, but i can't find much info on it online. I was also looking at the Asus Hyper card which has a fan as well, but finding that one in stock has been problematic.

Would you still recommend the CableCC despite them not having a heatsink or fan on them?4441

I probably would opt for a card with a built in fan, like the Asus or Dell, and the best price i can find for them is about $54. So that's doable for me. I just need to find out the dimensions of the Dell card so i can make sure it'll physically fit underneath my GPU, because that thing is a behemoth in the computer (I have a Dell GTX 1070 in there).
Thanks so much for your quick responses, i'm glad all this will work!

@the.mknabster , I would with certain configuration. I had one setup with enterprise SSD (SM963), so the heat does not affect the endurance (6TB DWPD) as it does when using client SSD. Also if the system use a single Quadro graphics and the other slots have enough space for airflow. The front fan (next to HDD cage) moves enough air to keep the NVME cool around 46 - 50 degree. But I just checked today and the price for Cablecc is double from what it was. Asus Hyper and Dell also are good choice if you can get them around 50 USD.
You are doing good right now by doing research and planning, be patient and wait for good price on the items you want.

Thanks for all information on this post since I am in the similar situation to upgrade T5810, there could be an option for Jeyi ihyper pro versions with aluminum case and fan, for its pcie 3.0 version, it's price is nearly one fourth of Asus M2 hyper from aliexpress. But it is still not right time to buy since price is roaring recently.
For T5810 pcie bifurcation, is it possible to see the options form BIOS or it is automatically recognized once you insert the expansion card?

@Thomas miao , IIRC it was recognized automatically. You would see all the adapters (with drives) in PCI slots as mass storage. Once in OS, you can see all your drives, depends on how many adapter and drives you used.

thanks again for your information. I am new to network. if the the 4 M2 drives are automatically recognized after booting to OS, ir it possible for me to reinstall freshly Win 10 on one of the Nvme drives or install on one big drive (raid 4 stick M2 together). if yes, any setting required at BIOS for Windows installation? Thanks.2534

@the.mknabster , they are designed as single slot cards and they will fit next to your GTX 1070.

Hi @the.mknabster , I can confirmed the T5810 does support bifurcation natively. It would recognize up to four NVME cards automatically. I don't know about the adapter you are looking at but if you check some of my recent posts on the same topic, I provided some links to similar adapters and you can check the reviews on those and decide which one to get.
You listed the slot numbering backward from the imprints on motherboard so it take a while for me to understand your current setup. Here is my thought, if you are using PCIe gen 2 slot, it will reduce the speed in half. Keep in mind that the NVME will produce lot of heat and if they are over 70 or 80 degree, it will throttle the transfer speed. So, get the adapter with cooling features (heatsink, fan).
Good luck with your project.
