Well, after doing some more digging, I found out that this drive is very limited in read/write speeds And I did find a nice USB flash stick testing tool called "F3" (for Fight Flash Fraud) See https://github.com/AltraMayor/f3/ Finally, I consider this problem solved.

Re: [PLUG] USB 3 port running very slowly - why?
How are you transferring? I have had experience recently with dd and not setting a "reasonable" block size, thereby relying on the default 512 byte blocks, which means LOTS of syscalls to do the IO. Setting the block size to something like 16M made it go a lot faster.

[PLUG] USB 3 port running very slowly - why?
Hello all: Someone gave me a PNY 256 gig flash memory stick, with USB 3.0 advertised. However when uploading to it, the actual rate varies from around 1.5 MiB/sec to 10.6 Mib/sec, which is way lower than the advertised USB 3.0 speed of 5 GiB/sec (? if we believe the information below) I ran the %lsusb command to try to see what is going on here. Any ideas on why it will take hours to transfer 208 gigs to it? - Randall -- information dump --- HP Z420 workstation USB Controller information --- SYSTEM: OpenSuse Leap 15.4 on 64 bit hardware Workstation has 2 USB3 ports and 1 USB2 port on the front panel Operating System: openSUSE Leap 15.4 KDE Plasma Version: 5.24.4 KDE Frameworks Version: 5.90.0 Qt Version: 5.15.2 Kernel Version: 5.14.21-150400.24.55-default (64-bit) Graphics Platform: X11 Processors: 6 × Intel® Xeon® CPU E5-1650 v2 @ 3.50GHz Memory: 31.3 GiB of RAM Graphics Processor: NV106 (from USB devices Info Center) xHCI Host Controller (3) Manufacturer: Linux 5.14.21-150400.24.55-default xhci-hcd Serial #: :08:00.0 Class 9 (Hub) Subclass 0 (Unused) Protocol 3 USB Version 3.00 Vendor ID 0x1d6b (Linux Foundation) Product ID 0x0003 (3.0 root hub) Speed 5,000 Mbit/s Channels 4 Max.
