Okay, so I got some time to do some tests and this is what I found.

I also changed the ethernet cable but the speeds were no different 🤷‍♂️ So it’s not the cable, especially as I can transfer out of the Dell. I just can’t transfer into the Dell at anything higher than around 25MB/s to the SSD and around 15MB/s to the 7200RPM drive.

Do we have any other ideas? Thanks again in advance

That’s a great shout, I’ll give that a try later on today and get back to you with some stats 🕵️‍♂️😁

I really appreciate your help

Thanks for replying 😊 My main copy program is TeraCopy. I drag and drop from my main server to the Dell, so no encryption. I’ve also tried letting good old Windows Explorer do the transfer but the speeds are the same.

I downloaded LAN Speed Test recently and it shows similar slow speeds the the Dell. I also set the network card to 1Gb full duplex incase, for whatever reason, it was resorting to a slower protocol but that didn’t make a difference either 🤦‍♂️😂 Pretty stumped
