TS-h973AX Slow Transfer Speeds to and from Nas - 200mbs

Post by hutber »

I have a 32gb TS-H973AX which is connected via the 10gbit card into my 10gbit network card via PCI-E 16x on my home PC. I have a 2TB M.2 pcie 4.0 drive which the files are then copied over into my Share Pool which are 2x NVMe drives.

The issue I am having is when transfering from with the M.2 or the 7200 RPM drives on the PC, I will never get faster than 200mbs for the transfering onto the NAS. The same happens if I transfer to the NVMe drives or the 7200 RPM drives on the NAS. Which is weird is, both the M.2 and 7200 drives have the same speed. Which makes me think its a Nas issue rather than an I/O issue from the PC.

So just for illustrative purposes:

| PC | Nas | Speed |
| M.2 | M.2 | 200mbs |
| 7200 | M.2 | 200mbs |
| M.2 | 7200 | 200mbs |
| 7200 | 7200 | 200mbs |

With around 40TB of files and the need to later video edit BlackMagic Raw 3:1 compression files I'll need to ** out some better performance if possible.

I am a little stuck now what could be limiting the performance.

I bought a 16gb h973ax 2 days ago and tested it with qts and hero with different hardware configurations. So far, very satisfied with the NAS and 10gbe switch (Qnap QSW-2104T), getting about 950MB/s with 3x1TB Crucial MX500 SATA SSD at RAID5 and over 1000MB/s with 3x1TB SSD at RAID0. I am still waiting for the U.2 enclosure to arrive so I can test it with an Adata sx8200pro 1TB NVMe. My test files are big compressed files 10-25GB each. Small files will surely be much slower speed

FYI, I tested transfer from NAS 2x8TB Toshiba HDDs at RAID0 to PC Gen4x4 NVMe, speed is over 400MB/s. Could it be something wrong with your switch? Sometimes, cables can be culprits. Recently found out my Cat5e that I have been using for over 10years (embedded into concrete walls during renovation 10 years ago) suddenly intermitently stop working. And then couple of days ago my USB 3.1 Gen2 cable that I have been using for over 3 years imtermittently gave me weird connection errors. Replacing both solved the problems. Previously, the last thing I suspect of anything would be the cables. Now it's always the first or second thing on my mind.

LOL. Last but not least, the first few days after I bought the 2104T switch, I sometimes cannot connect to the Internet and starting to suspect the Qnap switch was a lemon. Turned out, the cable between the switch and the router was the culprit. Replaced that cable and all things are back to the way it should be.

could you first SSH onto your NAS and run the following command:

Code: Select all

qcli_storage -T force=1

Code: Select all

qcli_storage -t force=1
Just want to see if your NAS is the issue or not.

Post back the results.
