    Question soft raid 1 performance

    Hello, all,
    I have a question about soft raid 1 performance, what's the normal IO speed for a two disk soft raid 1.

    We have two servers, and we have run following command in each server,
    dd if=/dev/zero of=test.bin bs=1000M count=1

    In one server we can get about 80MB/s, another one is about 40-45MB/s
    Which one is normal?

    If any one have similar setup, please let me know your result.

    Thanks.
