    thanks for the post that makes sense.
    thats true...forgot about that.

    Great Post... Thanks..
    A question, can you safely remove any Operating system files to increase free memory?
    If so million dollar question... which files.
    Cheers

    You'll notice the memory IC in the second pic at the upper lefthand corner of the board. It states that the IC contains 3 different types of memory:

    MoviNAND - the eMMC memory I was referring to. It is by no means slow (up to 52MB/sec) in its high-end configuration; but i'd be willing to bet that RIM is using the 1.8v x1 bus width configuration in the Storm (power savings and cost savings) - It's biggest advantage is high densities (up to 32GB). Also remember that the 52MB/sec spec is generally measured transferring one large file. A scenario which doesn't happen very often on a BlackBerry - so actual memory performance is likely to be much slower.

    SAMSUNG Semiconductor - Products - Fusion Memory - MoviNAND

    OneNAND - Acheives 2.8MB/sec performance in apps (actual performace vs. theoretical maximum). Available in 128MB and 256MB densities (sound familiar?) - optimized for copying from NAND flash to DRAM. Also has an integrated OTP block for enhanced security (could lead some merit to RIM saying they disable running Apps from anything but App memory) - unfortunately, only goes up to 256MB; that's why there is so little of it.

    SAMSUNG Semiconductor - Products - Fusion Memory - OneNAND

    Mobile DDR - a small-form factor version of the same DDR RAM we all know and love from the PC world. The actual system RAM, if you may. Unfortunately, the actual amount of Mobile DDR inside of the Storm (or Storm2) seems to be an elusive spec to hunt down.

    So it would appear that the memory limitations are both a limitation of the technology, and a security limitation. If the MoviNAND doesn't support the OTP block, then it's highly unlikely that RIM will ever allow apps to run from it; as security is their middle name.

    The iPhone likely has no need for an OTP block, so Apple is simply using 8, 16, 32, or 64GB of MLC Flash memory (same type found in consumer USB flash drives) for application storage. The parts breakdown for the 16GB iPhone 3GS shows the total component cost for the MLC flash to be $24; around what one would pay for an average consumer 16GB flash drive. Crazy enough, this is also the most expensive component in the 3GS.
    as far as i know, and your post supports me, the "secure" nand thats limited in size contains the OS and the apps, which are loaded into RAM on boot. (i asume that before the security check), then the mentioned check, surely controlls that the info loaded matches the one on the secure nand, or something like that.

    rim COULD make insecure apps not meant for the enterprise "storable" on the large nand, and only load them to RAM when needed, but that would be really not blackberry, surelly slow to open apps, and.. blablabla :P

    This is a great thread! I just read through it all and I feel smarter just reading it! I'm not being a smart ass at all. Reading through this helped to make some sense of some of the BB vs iphone diffs. Thanks!
