I've decided to never buy a USB flash drive again.
Now I'm using an SD card to USB 3 device. SD cards are so cheap these days that I'd rather just use those than have a collection of flash drives. It maximizes versatility since I can still use the SD cards in cameras, laptops, dashcams, or anything that takes 'em.
I bought a plastic "wallet" for holding SD and microSD cards so they don't wander off.
