NVME USB drives Realtek RTL9210/RTL9220 Firmware Version 1.xx

Yes, the problem can also come from the disk at the cache management level, check if you have the latest disk firmware

I will try to do something on it. Thanks again.

Would you mind me keep replying my topic in this discussion? I think it's not the Realtek Firmware issue at the moment but I am wondering someone could help me. Maybe I should register a Reddit account and take my problems there?

 

You can ask the question here, the forum is there for that. 

I've very bad IO performance with e.g. UAS-driver here in Linux even other USB 3.0 with my Realtek 9210B when fully accessing the device, e.g. "ddrescue  -f /dev/sdX /dev/null" (speed = 469MB/s) 
In comparison Asmedia 1153E (SATA-USB-adapter) tested good parallell IO also with UAS while fully accesing the device "ddrescue  -f /dev/sdX /dev/null" (speed = 469MB/s) 

My other NVME-USB-adapter with ASM2362 chip also has bad parallell IO over UAS while fully accessing the device.
The Asmedia ASM1153E firmwares have an MPTool-option "QD32=1" (standard setting is 0) I updated firmware using "QD32=1" ( "Queue depth" with 32 commands per queue?).
afaik SATA-AHCI has a queue depth of 32 commands per queue, and over UAS using SCSI similar. I have not found QD32=0x1 or similar setting on ASM2362 in the MPTool-config nor on any e.g. Realtek 9210B firmware's config.
I will add video later where you can see this, that with Asmedia 1153E with better IO-performance via UAS.

My Asmedia ASM1153E and ASM2362 support UAS also via USB 2.0, the Realtek 9210B does not.
The Realtek 9210B seems to not support UAS over in USB 2.0 High Speed mode, to only support UAS in SuperSpeed or SuperSpeed+., tested with 1.29.12, 1.33.44 and 1.33.98 firmwares e.g.

So i plugged my 9210B adapters in USB 2.0 port on my Intel Z77 chipset board, which does not use UAS with the Realtek 9210B via USB 2.0, but instead USB-Bulk-Only-Transfer,
...and the USB-storage-driver and with USB 2.0 speed the parallel IO is faster than with UAS+USB 3.0, while fully accessing the device: See video here for comparision:

PS: Google Chrome and other  browsers might say "this is an unsecure site", probably because ftp-server from my brother and father, it uses http and not https. So to see video, must say to the browser to make an exception, to view this content

You can see video via e.g. VLC player on menu left-top ->Media ->Open network stream (STRG+N) (CTRL+N)
