Has any one had any experience with Terramaster d5-300c 5 disk enclosure? It is connected via USB C - 3.1. I just unboxed it and am running a pre-clear at 44 MB/s. An identical drive, WDC-14TB being pre-cleared at the same time via another USB connection is running at 275 MB/s.  

 

Can someone shine some light if this is a normal speed for this enclosure?

 

Thanks,

I have attempted to use HDD/SSD via USB similar to this.

From old testing in 2009-2012
Unraid has a USB 3 generation problem when reading the flash drive.
USB speed will drop to USB compatibility of USB 2.0 speeds in Unraid which is why the drop. Unraid kernel to incorporate usb Gen 3 at the Linux kernal lay drops it to usb2.

Sadly, this is normal due to hardware limitation and software compatibility...


I'm trying to find the other post on the forum where i and other mods went over it. The gist from that posts was: has more to do with the hardware generations and the kernel setup that unraid uses. While it is possible to use and do this, it is not recommend due to the read/write speeds.

*will edit later with that post on the form if i find it again...

I was very confused and started trying other USB methods, which significantly bumped up the speed, and narrowed it down to one USB port on my case that was for some reason slowing things down. Once I switched to the other port, the speed went up in to 200's. I'll have to take the server apart to see where that port is plugged into on the motherboard. 

 

Thanks,
