Re: SSD performance article

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:
