Why are SSDs reliable for long-term storage, but USBs fail within a few years?

704 views

Since both SSDs and USBs use flash storage. I tried searching online and found [this thread](https://www.eevblog.com/forum/chat/reliability-of-usb-flash-memory-vs-ssd-drives/) and [this video](https://www.youtube.com/watch?v=IBz56HPO8SU), which were somewhat helpful but not entirely. Does anyone have a great analogy or digestible summary?

USB sticks are usually plugged and unplugged a lot more than SSDs, and I’ve seen the USB plug become unsoldered from its circuit board. I don’t know if USB sticks have wear-leveling, where the writes are spread out over different places so the same few sectors don’t get rewritten a lot, but I assume they do because even SD memory cards have wear leveling.
