Install an NVMe SSD on a Precision 5820 tower


I have a Precision 5820 tower that came with 2 NVMe SSD disks on the FlexBay. I have been talking to Technical Support in my country (Spain) to find out how to install a third NVMe SSD, but they have been so far unable to find a way. I am shocked that the 5820 is marketed as a highly upgradeable machine but no one in Tech Support seems knowledgeable on how to do it. Also, I am surprised that, despite having identified my machine through its service tag, Tech Support cannot retrieve its original configuration to suggest the necessary parts. I've been a Dell customer for 20+ years and as far as I know their customer service used to be way better than this.

Anyway, I purchased an M.2 NVMe SSD from Dell's web site, assuming that installing it would be piece of cake. I was wrong. It seems that the 5820 only admits 2 NVMe SSDs on the FlexBay. So, is there an alternative way to install it on my 5820, even if it's not on the FlexBay?

Many thanks.

You can easily add more NVMe SSD drives to the 5820 using Dell Ultra-Speed adapter.  

If you have trouble sourcing the Dell adapter, you can use easy to find Asus Hyper adapter.  Remember to install it on a PCIe x16 slot for all 4 drives to work (slot 4).

Thank you. I will order an adapter as you suggest.

You need the Intel RAID driver to enable the PCIe bifurcation. Probably installed by default by Dell, but if you've done a clean Windows install it's at
