Case: Meshify 2; front panel port is USB 3.1 Gen 2 Type-C
Mobo: Z790 Hero; case cable plugged into USB 3.2 Gen 2x2 Type-C Front Panel connector (U32G2X2_C9); a 6-pin PCIe power cable is plugged into the PD_12V_PWR header
When I use a Samsung T7 Shield external drive plugged into the front port on my case, the speed is extremely slow - in the kilobytes - and quickly the transfer halts, Windows says I/O issues, it just doesn't really work. If I try the same device and cable in a motherboard USB-C port, it works just fine. Bios, FW, drivers all updated. I've reset CMOS.
Visually, nothing appears wrong with the port nor cable:

this post and also wrote, "Cable is not issue, but port it is. Since port cannot provide sufficiently signal and power to any cable longer than a 5cm. So little cable will fix this problem. Just try it out."
This seemed unusual to me because the cable works just fine in a rear mobo port. And unfortunately, the only other USB-C to USB-C cable that I have is about twice as long (original that's included with drive on top):

Transfer speeds:
Original shorter cable plugged into motherboard: 350+ MB/s
Original shorter cable plugged into front panel port: Kilobytes then disconnects, doesn't really work
Random longer cable plugged into motherboard: 30 MB/s
Random longer cable plugged into front panel port: 30 MB/s
I then found a
forum post on the Samsung website about slow transfer speeds which states, "The builder of my computer says this is a known issue with the Fractal Case, even though Fractal does not want to readilly admit it."
Originally I thought that this may be an issue with my motherboard, but now I'm not sure. Perhaps the issue is with the drive cable or maybe it's the case cable and/or front port. Could be both? I'm just confused at this point.
Two Questions:
1) Can anyone confirm what is going on here? I guess the USB-C to USB-C cable that's included with the Samsung T7 Shield external drive is no good? But maybe there's also an issue with the case?
2) I'd like to use the front panel USB-C port, but the speed difference between that and a motherboard port is substantial. As someone previously commented that I quoted above, could a shorter cable increase the speed? I assume that included cable is no good, but maybe the other cable actually is too long? Or is the slower speed simply a function of either the front panel case port and/or the U32G2X2_C9 motherboard port?
Any other comments/information would be greater appreciated. I've spent I don't know how many hours trying to figure this out.
Thank you!
