I’m not sure about the bigger drives, but I have found most flash drives equally disappointing. The advertised speed is far from the actual transfer rates.
However, I recently purchased one of these usb 3.2 drives:

They are excellent! Truely exceptional speed and I can confidently do planetary high speed captures direct to the external drive too. Expensive, but office works will price match the Amazon prices…
Perhaps you can find a similar usb 3.2 device in a larger format but I’d say it’d be very very pricey.
