On The QNAP, make Ethernet port 6 (10G) - IPv4 STATIC. If you are getting 150 - 300 MB/sec, it is my opinion, that you are in a x1 lane PCIe slot with the 10G card in the PC. On the computer, open CMD, type in ping 192.168.2.3 On the computer's 10G port that is connected to Ethernet port 5 on this QNAP - make the IPv4 address of the 10G port on the PC STATIC IP> IPv4 192.168.2.11, subnet mask 255.255.255.0, MTU 9000 Make sure you are not sharing the 10G connection with the internet - no matter what happens, no matter what the conditions are. The 10G card in your PC must MUST be in a x4 lane PCIe slot. Storage Pool 2 - all 8 drives in a single RAID 6 configuration, thin provisioning.įeel free to update your QuTS OS to QuTS 5.0.0 (not a beta version). I'm at the end of my wits now, I hope someone can help me on this! Jumbo frames - tried different configurations - changing this only made things worse, left it on 1500 in the NAS and disabled on my Workstationĭirect LAN connection between NAS and PC - Same behavior, so it can't be our Switch Transfer via FTP - Exactly the same behavior - So it can't be SMB Tests with Pool 1 and Pool 2 - Both show exactly the same behavior/speeds - So it can't really be the HDDs or the RAID configuration Other PC - transfer speeds even slower with 500MBs write and 120MBs read - both use a TP-Link TX401 network card Iperf3 speed test from one Workstation to NAS - approx 7Gbit sender and receiver. I am of course aware that the speed is limited at around 1000MB/s due to 10Gbit network speed. In theory, the read speed on RAID10 should be higher than the write speed. This is well below the performance this setup should have. However, the speed fluctuates a lot, sometimes as low as 150MB/s. But the read speeds from the NAS to the PC are at 300MB/s max. When I copy a file with Windows Explorer or run the Blackmagic Disk Speed Test I get expected write speeds of around 900-1000MB/s. The NAS will be used for video editing on 2 connected workstations. The two SSDs are setup in RAID1 as pool 1 for the system and the HDDs in RAID10 as pool 2 for files. I have set up a new TVS-h1288X with 8x 6TB WD Red Pro and 2x 1TB Samsung 980 NVMe drives.
