A while back I acquired a NVMe caddy but did not get to use it. I now did as I got an NVMe disk.
The caddy is
https://www.aliexpress.com/item/1005001346524009.html
Color: 10Gbps M2PV C3
The disk is
1TB WD Blue SN580 NVMe WDS100T3B0E (PCie v4)
I expected to see 1GB/s speed.
Read [X=Y] cable from USB-X to USB-Y. Caddy on left, machine on right.
1) Directly connecting the caddy to the machine (caddy-[C=C]-socket) I see 36MB/s. So USB-2? speed.
2) Using a caddy-[C=USB3M]-socket I get 442 MB/s. So USB-3.0 speed. This is expected.
3) The kicker: caddy-[C=USB3M] then [FUSB3=C]-socket (two cables) I get the expected 1000MB/s.
I tried a few C=C , no change. Two different machines. same.
What I want, of course, is good speed with a straight C=C cable.
Maybe your straight C=C cables don't have the extra pins wired for the higher speed. What do the logs show for each of those connections?
I considered this so I tried 5 different C-C cables. Same results.
Note, this mobo does not have USB-C so installed is a PCIe controller.
$ lspci -v
06:00.0 USB controller: ASMedia Technology Inc. ASM3242 USB 3.2 Host Controller (prog-if 30 [XHCI])
It shows as USB bus 3 and 4.
/: Bus 003.Port 001: Dev 001, Class=root_hub, Driver=xhci_hcd/1p, 480M
/: Bus 004.Port 001: Dev 001, Class=root_hub, Driver=xhci_hcd/1p, 20000M/x2
Bus 1 and 2 is on the mobo.
I expect that the mtp/thunar messages are not relevant but I left them in.
Speed is from 'hdparm -t'.
1) Using the C-C cables, speed 33.64 MB/sec
