Yeah, I did try that, but it seems TOS 4 does not support NTFS. (I initialised the disks on a Windows 11 PC).You may consider directly connecting the D5 hybrid to the F5-221 and then transferring data straight from the F5-221 to the D5 hybrid. This approach could potentially eliminate any influences stemming from the network or intermediate links.
The F5-221 wanted me to initialise them, suggesting it does not support NTFS.
I ran a speed test over my LAN, and it looks like there was an issue.
I rebooted a router and am now getting 105Mb/s. Much better.
We are down to 7 hours for the remaining 2.5Tb of data to copy.
Many thanks for the prompt response.
