Thought I would share some additional information here to show people what the potential would be 2 or 4 of these drivers.
1 - ASRock ULTRA QUAD M.2 CARD PCI-e to 4x M.2 Card - $100
2 - Dell Ultra-Speed Drive Quad NVMe M.2 PCIe x16 Card - $199 - $250
3 - ASUS Hyper M.2 x16 Card Expansion NV Me M.2 Card - $45 - $65
4 - HP Z Turbo Drive Quad Pro Card - $750 - $800
NOTE:
When researching these cards you will see not so great reviews. These are from people with older hardware ( motherboards ) that are not compatible with any of these cards. However, the reviews are amazing from end users that in fact do have 100% compatible hardware. I wanted to point that out to the people that do not actually read reviews and instead just rely on Amazon stars, etc.
