Asustor AS 6510T full 10Gbe speed running write speed only 300mb/s

[linyifei2000]

first of all, my net environment:

1，Imac 2020， iMac (Retina 5K, 27-inch, 2020)， 3.6 GHz 10-Core Intel Core i9，128 GB 2667 MHz DDR4， AMD Radeon Pro 5700 XT 16 GB， Apple AQC107-AFW 10Gbe，

2，NAS 6510T, upgrade to 32G，Gigastone DDR4 16GB 2666MHz PC4-21300 CL19 X2

3，HDD， Seagate Exos X18 16TB Enterprise HDD X10

4，cable，Cat8 ，60 ft also 10ft has been tested，same result，

5， 交换机 TP-Link 8-Port 10G Desktop/Rackmount Unmanaged Switch (TL-SX1008)

6, Mac and NAS MTU set up to 9000，

in this environmental, write speed only 320mb/s, and read speed only 680mb/s

is that normal to everyone?

Your record is somehow lower than the record on Asustor's web site. However it depends on your test environment, although I think yours are pretty good. Anyway, if you want to boost the speed, you should consider adding M.2 cache which cost is cheap. And normally, your record should be much better (no M2. cache) if you fire multiple client PCs at the same time.

I had 2 x WD_BLACK 1TB SN770 NVMe Internal Gaming SSD Solid State Drive RAID 0, as cache btw.

no matter i use 10 Gbe switchs nor i directly put cable into the NAS 10Gbe port, it shows max 300mb/s

is that asustor supposed to be??? or i set up something wrong

mm... sounds weird. Did you use samba protocol to mount to your imac? If no, you should try it first.

I think you can try to create a volume onto M.2 devices first. Then do read/write test on that volume.

And you can try the other test: start AmorphousDiskMark * 4 on your imac. This should generate 4 io accesses to NAS at the same time (although I'm not sure in imac environment). If the sum of the total bandwidth is good, your problem should be caused by the IO latency on your imac...
