One would hope that cache on RAID cards would help reduce high frequency reads. Further IBM i's single level storage would also help mitigate this. If we read something a lot it will naturally be more likely to already be in main storage.

Reads are fine?

For all intents and purposes, I think reads are fine in real-world
implementations. From the pure physics of it, reading does have a
more-than-zero chance of causing ill effects, but the controller
should be able to compensate:
