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

700 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?

USBs are manufactured with plastic using ‘OXO’ technology. Basically, this component induces decomposition of the product earlier than it would on own.

This decomposition, as others have pointed out, will bread solders and such, which with unable USB for use.
This, of course, forces you to buy a new USB to replace it, thus creating new business for the manufacturer.
