    Seriously.
    What is is the advantage of the cache2cach? One I know: the easy switch between various ROMs and to Froyo. Other than that?

    It boils down to this: Is the internal storage of the phone different from the SD card. I *think* both are built on the same technology, so they should not be different as far as reliability is concerned. (limited number of write cycles...)

    Any thoughts?

    The cache block of storage in Android is underused, so moving Dalvik there (so long as it works, and it seems to) is a brilliant hack (using the word hack in all its positive meaning) and saves you a block of unused space of SD, too, as well as the time and angst of backing up files, partitioning, moving files back, etc.

    Unless you have a class 4 or 6 SD card, I believe that writes to internal storage are faster than to SD (though, of course, the great value of caching is in reading rather than writing.)

    (I have a class 6 micro-SD and I just ran a benchmark against internal NAND, and the SD is slightly faster. It would be interesting to compare the stock micro-SD that came with the Eris, but I just don't feel like taking my phone apart.)

    doogald, you are right. Moving the Dalvik area is indeed a great idea, maybe it should have been there from the beginning.

    Your observation is really interesting that a higher class SD card in combination with apps2sd might be faster than the cache2cache that uses a slower (internal) memory.

    I have a 16Gb Transcend class 6 card, so I might be better of to stay with apps2sd.
    BTW, the 16Gb Transcend class 6 card is hard to purchase - Transcend is getting out a class 10 card to replace it.

    Was just surfin around this evening and saw your post and wanted to mention, if you have not already thought of it, that you need to make sure that you run your cache2sd as well to gain speed ;).

    Before cache2cache I personally ran my apps2internal and the cache2sd :)
