is anybody using USB Hub‘s to connect more than one external USB 3 HDD with a Server?
Right now I am running two external nodes that are connected to my Qnap-NAS via USB 3. the Qnap has enough memory and CPU power free to run many more nodes, but unfortunately only has 2 x USB 3 ports…
How would you extend the storage?
I know that there is the official qnap expansion box, but that‘s so expensive… I think by just adding another external USB 3 HDD I can save a lot of money, but I don‘t know if this will work. Will it increase my IO waits significantly?
From what I have read so far USB port isn’t meant for 24/7 usage. In many cases it was the cable or the port that got the disk disconnected. Preferably use Sata port if you can.
There is no problem in connecting a lot of USB 3.0 storage, every NAS have good USB controller for transfering big amount of data.
If USB 3.0 device supports UASP mode, than IO waits will be normal.
If it was true, keyboars, mouse’es, printers and many other equipment would fail. NAS & router manufacturers would not implement USB ports for external drives and etc.
