For my experience of USB2 memorysticks, you can have a huge difference
in performance between makes. Note that "branding" has little to do with

Sorry but it is a bit of a web search to see if you can get any useful
comparisons/comments. For example years ago, "Super Talent" and
"Intenso" were clear speed leaders for their USB2 8GByte devices. Then
again, times change quickly.

For USB3: I've only got the two of them and they work fine on a USB2
system. I'm experimenting with F2FS with good results so far.

My experience has been memorystick wear-out after 3 months of ext4 on
raid1 (two devices) vs over two years for ext4 (non-raid) with good use
made of tmpfs for busy areas. That was for a school server and a certain
web server...

Bit rot was seen after about a year if the data is not rewritten :-(

(Now on SSDs 'cos they're so cheap as to why not! :-) )

There is this media player RasPi with a USB -> sata adapter...


Do not be tempted to use a USB HDD... Premature death by spin up

Have fun!
