Web Hosting Talk : Web Hosting Main Forums : Dedicated Server : soft raid 1 performance

[pedro2010]

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.
