Personally I suspect this issue is inherently about how Linux Kernel handle the UASP or USB 3.x in general but who am I to speculate.
I am really not sure but also feel that it is something outside the sphere of the Rock or just this kernel.
http://linux-sunxi.org/USB/UAS gives some info.
I have a hunch a lot is about power available and that devices might have the required power requirements but when you go down long leads, multiple connections and various thin tracks, if the end device gets the power its needs anything up to 900ma with a HDD is debatable.
My Rock should be soon as a 7th Aug purchase and it would be really interesting if people could publish results.
Many say no to UASP multi adapter RAID but if it could for many that would be pretty tremendous.
I have a feeling the Armbian / OMC guys may of already done this to death.
I have lined up to test 2x https://www.amazon.co.uk/Inateck-Adapter...B074M1G9KD with 2x WD 640 Gb as have 4 of them here.
They are the ASM1153E chip with UASP as the http://linux-sunxi.org/USB/UAS " (most probably they need quirks too as those already listed in **unusual_uas.h**)" whats that then !? Dunno.
I just don't have 4* 2.5" of the same avail so going with what I have and a 3.5" capable adapter which might be interesting as its powered.
Also with hubs as there is a lot of nasty cheap stuff out there but going to hang them off a reasonably decent powered hub
Need to purchase a ORICO Aluminium 12 V 7 Port USB 3.0 Hub with 2.5 A Power Adapter Silver A3H7 with Via-Labs VL812 chip £20
I am going to try RAID 0, 1, 10 and will post my failures
Just need the Rock64
