Guys,

I have received and configured my new QNAP TVS-873e with the QNAP QXG-10G1T card. I have it set up in Raid 6 as a Static Volume and have allowed it to synchronize overnight. I have the iMac Pro connected directly to QNAP via the 10 GBe ports.

My speed testing is returning similar results to the previous QNAP 831x. The IOPS results for each of the isntalled 8 drives is 175 so, the max available bandwidth from the drives should be 6×175 =1050 MB/s in Raid 6 (I realize this is a theoretical max that I will likely never see) however, I am only seeing 370 MB/s Write and 430 MB/s read speeds. I was getting <300 MB/s Write and 480 MB/s Read with the previous QNAP system.

Comparison
QNAP TS 831x <300 MB/s Write 480 MB/s Read
QNAP TVS-873e 370 MB/s Write 430 MB/s Read

I am guessing there is a bottle next somewhere else in the system? Any other ideas on what I can try?

Thanks for you continued assistance!!

Mike

Yes, thank you Bob for your expertise!

I have struggled for a couple weeks trying to figure out why I am not getting decent speeds and now I know that it has to do with the limitations of the 831x and network card. I am returning the old hardware and per Bob’s recommendation, have already ordered the TVS-873e and 10G QXG-10G1T network card. I will be configuring this week and will report back.

Mark, as Bob has said in his previous posts, stay away from the 831x and save yourself some trouble.

Thanks again Bob!

Bob and Mark,

This is a timely discussion however, I am already down the road a bit as I have already purchased the TS-813x. Here are the details:

TS-831x 4GB ($799)
QNLAN10G1TA 10GBe network card ($139)
8 x 4TB HGST 7200 drives in Raid 6
iMac Pro w/ 10GBe

The iMac Pro is directly attached the the network card in the QNAP via Cat6. I am getting pretty slow speeds, or so it seems to me, <300 write / 480 read. Seems that with 8 drives (N-2), 6 drives after the Raid 6 that I should be getting 600-700 read/write? Bob, is this because as you said the 831x is extremely slow?

If I return the 831x and upgrade to the TVS-831e (couldn’t find this on QNAP’s site so maybe you meany the 871e?) and the different QNAP QXG-10G1T network card, will I see better speeds via direct connection to the iMac Pro’s 10GBe?

I am looking to use this as a NAS located in a different room about 60 feet away via Cat 6 and want to use it to both store and edit video from.

Thanks,

Mike
