USB 3.0 Transfer Speed with external memory devices

[Ink stained Fingers]

This USB hub comes with a type C/USB3.1 connector and a 5V/4 Amp power supply, it can thus support multiple external
2.5" HDD's for copying, mirroring etc, the USB 3.0 ports are running up to 390MBytes/sec with a M.2 SSD; it is one of the better equipped and performing USB hubs with 7 ports I have seen so far.

The USBTreeView utility as listed above gives you a myriad of information you most likely never wanted to know.
There is a nice little utility which focusses on the more important data, all available hubs and ports and connected USB devices with their vendor and product-ID

https://www.the-sz.com/products/temple/ for download
The USB biotop is huge, but getting good data is not that simple, all USB devices are uniquely identified by a vendor and product ID and a serial number - VID and PID which are listed as well in the Windows device manager.
https://docs.microsoft.com/en-us/windows-hardware/drivers/install/standard-usb-identifiers

The PID and VID as displayed by the Temple utility can be used to search this database
https://www.the-sz.com/products/usbid/ to get more detailed information.
It can help you as well with trade name relabelled USB sticks displaying you the actual vendor info.
I once had a USB to SCSI adapter lacking the driver, there was no marking or anything on the device, and the search for the vendor via the VID got me to the manufacturer and finally the driver.

This utility does not give you any manufacturer's info for SD cards attached via an USB card reader, SD cards are not USB devices. There is a 'SD Insight' app running on some Android versions doing this, but I could not find anything similar for Windows.
The SD memory card market is flooded with fake cards from the Far East which are not easy to identify in some cases.
I have a card promising 512GB for a vey low price,

looking up the info 'AX215F' reveiled some interesting information, it is a controller chip for SD memory cards well known here
https://www.usbdev.ru/cics/icappotech/ so far so good, but

with a remark copied from there
'Huang explained at the conference that with flash memory you are not really storing your data; what you are storing is a probabilistic approximation of your data.

“The illusion of a contiguous, reliable storage media is crafted through sophisticated error correction and bad block management functions,” Huang explained in a related blogpost. “This is the result of a constant arms race between the engineers and mother nature; with every fabrication process shrink, memory becomes cheaper but more unreliable. '
(which might contradict some advertising of the major card manufacturers)

Don't read any further

and the AX215 chip was already mentioned here some years ago

So I only can advise everybody to buy genuine brand name cards like from Samsung, Sandisk etc, and these from reliable sources only , faked cards can be quite sophisticated already
