I have a ToughArmor MB699VP-B.
I know the maximum speed of the device is 32Gb/s, over PCIe 3.0.
But the miniSAS HD (SFF-8643) connector supports up to 48Gb/s
Not as fast as PCIe 4.0, but faster than PCIe 3.0.
I guess this is a bit of a long shot, but could I expect some speed benefit If I use the device with a PCIe 4.0 motherboard and a U.2 PCIe 4.0 SSD, like the upcoming Samsung PM1733.
