so i got the contraption and it seems to work ok but in-camera performance looks just like the cfe-b cards for both the T705 and the 970 EVO+, which is to say, it cannot run without buffering, with both lossless and he* (you will see the buffer creep down to 0 and then some sputtering. it can *almost* keep up with HE*, but it does not keep up. if it could keep up, the "r"emaining counter would never get to 0)
settings are visible in case anyone spots issues. af disabled, flicker disabled, iso set to manual, 1/3200s.
i may do some benchmarking of this setup out of camera just to see how far the current fast cards are from desktop modules, but so far, all evidence suggests the z9 cannot currently sustain 20fps indefinitely and the likely culprit is the camera, not the cards.
i'm still wondering if there is only one pci lane in use here. my seat-of-the-pants tests suggest it can sustain about 15 fps, maybe a tad slower, which works out almost exactly to one pci lane's worth of bandwidth (note this would be similar to like a Raspberry Pi 5, which supports nvme with a single lane)
