I am planning to get an external storage for Ventoy use. My current random usb 3.1 stick writes .iso-files with only 10-15 mbps only. I found this webpage for usb stick speed comparison: https://ssd-tester.de/usb_stick_test.php
The fastest usb sticks writes 800-1000 mbps in the crystaldisk-test.
If you have personal experience on this, please recommend which approach is better.
I have a 32gb USB flash drive I got from Protectli with some other purchases I mad (it was cheap and is tiny and metal) I was surprised how fast it was, so I am using it for my ventoy boot disk and have 15+ isos on it.
I actually just used it last night and copied windows10, debian 12.5 and Linux mint isos
They all copied pretty quickly!
