Don't have an SSD? Create a RAM Disk with your extra RAM.

  • As part of our ongoing effort to make Isadora 2.0 the best release ever, I've been having an interesting back and forth with Tom Butterworth, who in tandem with Vidvox, create HAP. A user was not getting the playback performance he expected, and so I did some tests and I wasn't getting good performance either.

    Long story short, my lame 5400 RPM hard drive was the culprit. It maxes out at 33 Mb/s according the Blackmagic Disk Speed Test, and the four HAP movies we were trying to play require 40 Mb/s.
    On a whim, I took a stroll down memory lane, back to 1990 when using RAM Disks on the original Macs was all the rage, and created a 2GB RAM disk on Mac OS X.
    (It's incredibly easy to do: see
    Suffice to say, performance is pretty darn good -- which is one would expect given that nothing is going to be faster than RAM -- no even an SSD.
    So if you are SSD-less, and can fit your clips into some of the 8 or 16 Gb of RAM you have on board, it might be an interesting approach to try.
    I'm sure @DusX can tell us how to do something similar on Windows.
    All the Best,
