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.
