SSD nvme for Precision 5820.
Good evening, I purchased a 5820 workstation with a Dell Ultra-Speed Drive Quad and a 1TB NVMe Class 50 drive, which is configured as a bootable disk. In the future I plan to add another 512GB card to the Dell Ultra-Speed and that's my question. Won't I have compatibility issues if the SSDs have different storage capacities?
I think about this because in a few years the M.2 SSDs will certainly be the standard to replace the HDDs and I would like to keep my Dell Ultra-Speed Quad compatible.
I'm going to take the opportunity to go a little further, as I bought this workstation with a view to having it for many years to come. Will it also support the new Quadro video cards?
My 5820 has the 950W Chassis.
Thank you very much.

You will not have issues mixing different sized drives because each NVMe socket has a 4 lane PCIe to itself using PCIe bifurcation that enables the card in x4x4x4x4 mode and totals x16PCIe lanes used by the card when it is full.
It does not matter what brand of NVMe PCIe drive you want to use but it cannot be a M.2 SATA model as far as I know.
M.2 supports both SATA and PCIe storage interface options but the quad port card you have is PCIe only.
You can set drives in RAID 1 or 0 or 10 but you will need the VROC key to keep it bootable. You can mix RAID using the other sockets if you wanted a three drive RAID0 for example
Your system will be able to use any video card you choose, GTX, RTX, Quardro or any AMD workstation or gamer oriented card. You will find that you have two PCI 6/8 pin power cables in your case ready to use, even if you have a video card that does not use the power cables from the Dell factory.
