Ahh, yeah. Neither would I. I would expect my USB sticks to last longer than that, lol.
That aside - here’s a fun fact. We sell the NAND from scrapped SSDs that we no longer need for development to a third-party vendor that actually desolders it and uses it for flash drives. So… you never really know what kinda flash storage you get on your flash drives! (Or… we did do this, until the program recently got shuttered because NAND is so damn cheap now)
I’d personally be super surprised if they were outsourcing their firmware engineering - but I do suppose it’s technically possible.
