Would Lemmings be so kind as to post their USB-A/C memory sticks of choice?
Right now I have a small collection of Kingston USB drives I bought a decade ago. Haven’t had any issues with them yet, but I know they won’t last forever. They’re all named Reebok[storage capacity] (because sneaker-net).
I really like what explainingcomputers did for their pi4 build, where they basically convert a m.2 SSD into a big usb thumb drive with a simple metal enclosure. Check it out, the timestamp you want is 6:25
I went this route as well. You can get a good quality usb 3.1 portable nvme enclosure for ~$20-$30 (be careful not to accidentally buy the msata version, which is cheaper but slower). Now you have a very fast thumbdrive! The main drawback is, unlike traditional thumbdrive, I can’t use it on my android phone. Not sure if higher end phone with usb 3.1 port can actually use it.
Your Android phone can mount an external drive enclosure over OTG, just make sure it’s compatible and formatted properly.
With everybody and their grandma shoving their cloud into your face, I’m happy there still are flash drives for sale.
