A couple weeks ago I chronicled my disappointment at the failure of trying to use a supposedly compatible SSD into my G4/550 Pismo. That might deter some people who have more sense than a crazy hobbyist like me, but I'm thinking on it some more. A little performance boost over a mechanical device would be nice, but more than that I'd like it to run cooler and use less power (given how scarce good battery power is for the Pismo now). I've decided to try another approach: instead of a regular SSD, I plan to try a Compact Flash card using a cheap CF to IDE adapter. I doubt I need more than a 64GB card; in reality even 32GB would probably be enough but I don't expect the price break on the smaller ones to justify it. That said, I'm learning about CF cards and such and I see their throughput ratings and such (i.e. rated MB/second or multiples like '400x' or '800x' or '1066x'). So my question is, if anyone has played with this stuff, for something like a Pismo, how much is overkill? I'm willing to pay a little more for faster as long as the innards of the Pismo can keep up. Once a card is faster than the data bus can practically transfer in reality, paying more for a faster rated CF card is a waste of money (apart from the potential of using it again later in a faster device). For sure I'd think anything rated more than 100MB/sec would be wasted on this, and for practical purposes, even half of that might be sufficient given the limited data bus. Does anyone have any practical, real-world experience with this sort of thing?
