This is the very same server with the same drives - I just unplugged the USB stick with Unraid on it and booted from the SSD where I was testing TrueNAS from. I re-created a pool and a share and transferred similar files - they're video files so pretty large. Same macOS computer of course. There's something with Unraid - either macOS doesn't like it or Unraid doesn't like the HW of my little NAS.

I can understand the speed drop but transfer stopping altogether for like a minute when transferring? This is only happening in macOS apparently.

Interesting. And this doesn't happen on a more traditional RAID-5 or TrueNAS because Unraid is not striping the data across multiple drives? Update: So the issue where the transfer pauses for quite some time only happens in macOS. While it's paused, I do see activity on the array but not necessarily at full speed. The tunable didn't make a difference, at least in macOS. This is what my Ethernet looks like when transferring. Sometimes it does slow down as in Windows but most of the time it just stops! That graph is pretty slow, I reckon there are 1-2 minutes between those chunks!

I run some transfer and noticed a similar behaviour so I turned off all my IP-based camera and the OMV NAS started transferring at full speed with no glitches, see below Then I tried the same with the Unraid server - it's mostly identical, a bit faster, and somehow the transfer slows down after a few seconds Weird behaviour for sure. any ideas?

Thanks. I tried again, it didn't fail but it's been hours and it's barely moving. I hope this is enough to highlight the problem. I stopped the copy just before extracting the diagnostic package which is attached. Thanks again n54l-diagnostics-20251127-1515.zip

Hi all, I'm trialling Unraid 7.2.2 on an old HP N54L Microserver, 16GB ECC Ram, SAS2008-IT controller. I fitted 4x2TB HDDs which are old and not entirely reliable apparently but they were working ok with TrueNAS on the same machine. I'm just testing Unraid to decide what to install in the end. I think I've managed to create an array of drives and I can access it from macOS. However when I start copying files, I see 100% network activity for a few seconds and then it stops, then a minute later I see another burst of activity and then it stops. Eventually the copy fails altogether. I would like to find out what's going on, can someone point me to the right direction please? Thanks Tony

Hi all, I have a Fujitsu D2607-A21 card which I need to flash to IT mode and I have been reading and reading around to understand what the process is. Thanks @FingerlessGloves for the guide and @lrq3000 for the updated version. I have one question, for my own curiosity: why do we need UEFI and non-UEFI systems to flash those cards? Thanks!
