5. Running at 500/900 is fast, but, it's a fairly conservative improvement on the 500/805 that I was running before. Testing with 500/1100 feels really sleek - I really want this, and I accept full well that it's not optimal for battery life or (possibly) for device lifetime. I remain interested in achieving this on a transient, as-needed basis. In doing so, I'm also seeking to mitigate the impact on battery life by applying this on an as-needed basis, and should add some kind of safeguard against remaining in 1100MHz mode for too long in case of constant loading. What else am I not aware of?
6. Does the proposed benefit of this come from the assumption that the microSD card is fundamentally faster than the eMMC (not sure mine is), or from the fact that it is a separate device? I'm not filled with confidence by this thread either, is there a material benefit to this?
