Is this a hallucination? What am I missing? Why would heavy reads generate writes?

- TacticalCoder 2mo ago> Is this a hallucination? What am I missing? Why would heavy reads generate writes? I take it heavy reads means more stuff goes into RAM, meaning other stuff has to be cached? I've got same question as GP: e.g. is there a way to set moderately fast consumer NVMe SSDs (I've got both a Samsung 990 Pro and a WD SN850X) in a complete read-only mode to prevent "wear"?
- fallingbananna 2mo agoGood catch! Disk reads do generate writes to cache. But the cache itself is in RAM, not on disk. So it shouldn’t cause additional wear of SSD.
