I'm looking for a decent USB to use for general use(I might not even use it and forget about, I really just need it for installing windows 10 on my new PC I'm going to build). general use meaning transferring files for school, maybe the odd music file. A lot of sites recommended the Extreme usb with is world record setting speed but I'd have to get the 16GB and even then it costs more than it is worth (£13) (I know this is not a lot of money but i might not use it regulary and i Don't know if the Godly speed is worth it) and it's 16GB, I could get a 32GB ultra for £7 (or a 16GB for £2 less).
So I ask you fine people, what should i get?
16GB Ultra? (£5)
16GB Extreme? (£13)
32GB Ultra? (£7)
