Troubleshooting • Re: RPi 4 NVME over Network transfer speed issue

Thank you for the help:

Code:

dd if=/dev/zero of=foo.dat bs=16M count=128 oflag=nocache128+0 records in128+0 records out2147483648 bytes (2.1 GB, 2.0 GiB) copied, 53.9675 s, 39.8 MB/s

Seems a lot lower than expected for an SSD.

Performance problem identified.

I don't fully understand why the results of hdparam and dd are so different. I've ordered a new 10gbps usb-c to A cable and will retest once it arrives, I'm generally dubious of the current setup since the C-to-A adapter I have has USB 2.0 speeds when the C side is plugged in a certain orientation, very weird.
