Speed is the absolute only thing that matters (although I need at least 64GB of storage and the highest capacity is ideal, I can always get multiple). Currently I only have USB 3.0 ports (20 of them actually), however, I will be getting a new computer soon but if you’re only going to give one reccomendation I want the one that will work with my regular USB 3.0 ports. I demand a SanDisk because I have always trusted them and they are reasonably priced. Currently I have a SanDiskCZ80 64GB. https://www.sandisk.com/home/usb-flash/extreme-usb
in that case you can check out the extreme pro 128gb usb 3.0 flash drive that is the fastest model sandisk produces at the moment.
