I need some help, I must be doing something wrong with my rock...
Let me explain : I bought an adapter with an ASM1153 chip which normally is OK on the UASP side. I plug a SSD (on the USB3) and I'm doing some copy speed test and it's... slow. Copy cant' reach 30MB/s on 2GB+ file ?
I can't understand how you can get 60MB+/s.
Is there some magical parameter to fine tune ? Some voodoo dance to perform ? Some goat to sacrifice ?
Code:root@rock64:~# lsusb -t
/: Bus 05.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 5000M
|__ Port 1: Dev 2, If 0, Class=Mass Storage, Driver=uas, 5000M
/: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 480M
/: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=ohci-platform/1p, 12M
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=ehci-platform/1p, 480M
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=dwc2/1p, 480M
So it seems it should be working but it's not.
As you can guess I'm a noob but I try.
To verify if the hardware didn't have any problem, I tried the SSD with windows10 and the same adapter and I can reach 100MB+/s on 4GB+ files...
Thanks for your help (and your patience).
Where are you copying the file from? If it's the SD card, then there's the problem. the SD card interface on the R64 is pretty slow.
Source is from one of my SSD and for the moment, it's an SSD which is plugged on the Rock. Network is gigabit of course.
