It looks like this isn’t as fast as the theoretical top PCIe 4.0 performance?

  M.2 slots are x4, and going by the table on Wikipedia[1], that equates to about 7.8GB/s for PCIe 4.0. Of course x8 could do it, but that would be awkward. From the table we can also see the prototype SSD hitting nearly 90% of the 5.0 max speed.

    M.2 is no longer used for enterprise drives like this. This prototype and the current model it's being compared against are 2.5" drives using the U.3 connector, and the power consumption is well beyond what the small M.2 form factor can handle. But you're correct that it's a PCIe x4 link, and that's what determines how much performance the rest of the SSD is designed to provide.

      Good catch, I assumed since it was a site named "noteboot check" that reported on it and they didn't specifically mention enterprise that it would be a high-performance enthusiast-level drive.

        They do all kinds of other stuff nowadays. First they added desktops than smartphones and now they review even vacuum cleaners.
