@nazokiyoubinbou @gloriouscow Mostly agreed, but simply powering an SSD doesn’t help for the majority of devices. They’re not refreshed like DRAM. Instead, SSDs made since roughly the advent of wear leveling store data with some error correction data. As blocks are read, the controller measures how much of the error correction capacity is used to clean them up. Above a certain threshold, the data is rewritten (probably to a different page, as decided by wear leveling). *Some* SSDs have a sort of patrol scrub which reads the whole drive in the background over the span of a few days. Most don’t do this.
