  1. Does anybody remember?

    Does anybody remember what the read write spped was for Floppy drives?
    (Someone asked me this, as compared to zips,CD's ,DVD's, HD's)
    I remember that under win95 there was a big speed improvement (32 bit drivers) as compared to DOS.

    What I know so far

    CD 1x = 150kbs
    Zip drive = 600kbps
    DVD 1x = 9x(CD 1x)=1350kbs
    help me fill in
    Dos floppy =?
    win 32 floppy=?

    As you can see it's not life threatening, but I want to know

    For Windows floppy speed you could try it on Sisoft Sandra. I have no idea how you could do it in DOS.

    That's a good way to find the speed of my drive.
    but I was hoping that someone had reference to the standard as the number I listed are max. speed, not real world performance

    I don't know about the drives, but the controller itself is rated 500kbps to 1mbps for most modern floppy controllers (Double density).

    Older models are somewhere around 250kbps (The ones made around the single density era), simliar to what 5ΒΌ transfer rates used to be.

    This is just the for the controller itself... Not the actual floppy disk. Judging by how fast mine is, I'd say it can't be over 100kb/sec. :dead:

    100 to 125kbps is about what I guessed.

    Ok dug out an "old " book (1995)
    High Density 1.4meg 3.5 floppy AT controllers were 500,000 bps constant speed devices

    I was under the belief that the floppy drive speed was equal to the 1x CDrom speed.
