I have a MacBook Pro with macOS on it. I am going to get my windows boot drive to work again today, and try it with that.Bob Zelin wrote: ↑Fri Sep 06, 2019 6:54 amit sounds like you have a Win 10 PC with a thunderbolt 3 port, and you are using the OWC T3 to 10G adaptor. I have no idea about your PC. If I am wrong, and you are using a Mac (you just said about the macOS SMB client) -
make sure to have SMB signing disabled in terminal, and reboot your machine. And enable Jumbo Frames in both System Preferences for your 10G port, and on the QNAP 10G port.
Why are you only using 6 drives in a TVS-873 - put eight drives in there. If you follow my instructions, you will get 800 MB/sec (and probably not more than 500 MB/sec write).
And stop staring at the specs on the QNAP website (2300 MB/sec) - I have no idea of what they are referring to. With a 10G connection, even theoretical bandwidth can never exceed 1250 MB/sec, and in real life, I have never
seen over 1100 MB/sec on ANY 10G client - no matter what. 2300 MB/sec probably means total aggregate bandwidth - and there is no way that a TVS-873 is going to perform like this. There is real world, and there is fantasy.
I am of course not expecting the QNAP website specs - they used a RAID5 with 8 ssds and a dual 10GbE link (link aggregation) [And with that, their speeds are actually possible]. But since, the RAID controller seems to be able to do that, and since internal speed tests reports speeds of around 10GB/s on my setup currently, I was simply expecting to get ~900MB/s read on my client machine, especially since the 10G connection appears to work correctly (9.88Gbits/s). Jumbo frames are enabled and SMB signing is off.
I actually am kinda fine with 550 and 400, but today noticed speeds dropping significantly when the qnap cpu is under any load. Did I simply buy an underpowered NAS? (When running a Virtual Machine on another Volume (M.2 SATA SSD) speeds drop to 220 read and 200 write, which is quite disappointing). I think I was just misled by the specs on the qnap website, thinking this NAS is ok for me since they showed it able to do way over 10Gbit/s.
If what I want is impossible with this NAS, could you recommend me a NAS model that CAN actually reach 10Gbit/s with a 6-drive RAID5? And also, I see no reason to use a RAID6 for stuff that is backed up somewhere else anyway. RAID6 is still not a backup.
