1969.2 MB/s includes overhead for PCIe protocol. Not all of it can be used for actual data. Therefore, 1500 MB/s is reasonable.Anyone else tested NVMe speeds in the 3rd slot that shares with PCIe x4? I can't afford to loose any SATA ports right now, and PCIx4 should do 4000MB/s so I figured that should be plenty.
I do have a PCI card in that slot, and according to the manual it should reduce to PCIe x2 speed in that case which would be 1969.2 MB/s according to this https://en.wikipedia.org/wiki/PCI_Express.
But Blackmagic Disk Speed test on reporting 1500MB/s which is a whole gigabyte per second less than the Sabrent Rocket's rated speeds. Does that sound right?
