Does anyone have a ball park speed comparison between a modern physical disk drive

  • 0

Does anyone have a ball park speed comparison between a modern physical disk drive and the flash drive on iPhone/iPodTouch? What is behind this question is this: I want to pull images from the cloud, park them on the flash drive and then sequence through them as a flipbook animation keeping as few images in RAM as possible so as to keep my memory footprint in check.

I would appreciate hearing from folks who have perhaps been down this road. Perhaps there is an open source library that already does this? Dunno.

Thanks in advance.

Cheers,
Doug

    As others have said, the local filesystem is much faster than your network connection, so what does its exact speed matter?

    For an example of implementing a flipbook-style animation, see the second code example on this page, which was pointed out in response to this similar question. In that question, Mo DeJong reports animating 480×320 images from disk at 15 FPS.
