I have a fairly old one I got a long time ago. I don't even remember exactly when I got it, to be honest. I think somewhere around 2008 if not earlier.
It's a 2GB drive and for some reason, files on it began to get corrupted randomly while it wasn't being used and kinda just being there. I copied everything off of it and removed what was corrupted, but the drive itself seems to be working fine regardless. I re-used it to make a linux live usb a while ago and everything's still intact on it so I'm not sure what the deal was.
I have another 2GB one, a Kingston one, it's green and white. That one is really shitty. Absurdly low read/write speeds and I don't even know why. It wasn't like this originally.
Got a 16GB one now that I don't really use anymore because I just keep everything on my computer itself now, given I have my own. It's some kind of Duracell one, I'm not sure where I put it,
The first one got really dirty because I left it somewhere for a long time and it became really disgusting... Like lots of dust and crap got stuck on it and it feels sticky, yuck
