Hehe at least something was learned from today(mainly me learning). All looking good now, I had a spare 256GB SSD laying around so i used it to test the USB2. Now the question is..... do I stick with your OMV image, or go back to Armbian_5.30_Orangepiplus_Ubuntu_xenial_default_3.4.113.img ?

Thanks again for all your help and really sorry for wasting time as it appears to be a hardware limitation - I should have spotted this earlier.

Oh - i see the issue here Samsung klmag2wepd-b031

Starting to wonder if the Samsung klmag2wepd-b031 eMMC chip is counterfeit?

Yes home is the eMMC mountpoint, i have no other storage attached. I used the nand script to copy your image to the eMMC. I will test now

The read speeds from the Pi have doubled with your OMV Image, however the write speeds are around the same. Spikes high then sits around 12MB/s. This board is starting to annoy me, is there a better one i can buy?

Excellent, I will try after work finishes. Thanks again for your help

https://sourceforge.net/projects/openmediavault/files/Other armhf images/OMV_3_0_88_Orangepiplus_4.13.0.img.xz/download <-- Assume i need to use this one?

Tested sudo cpufreq-set -g performance and it made no real difference. I don't actually need to use Samba, i was just using it as a test platform. As i was noticing similar performance issues when using wget & ftp etc, which lead me to where i am now. I will try your OMV image to see if it makes any difference. Failing that, what other boards are there that will perform better than this one with Gbit ethernet?

Thanks I will test that, I don't think it's SMB that's the issue, it does exactly the same over FTP. Yup I did reboot I will text the cpufreq now

Thanks, this shows me another person seeing similar issues to me... but I don't see the root cause or solution in the thread?

Also just conducted another quick test, I put cooling on the CPU and kept it around 35C, still get the same results.
