How would I measure the disk read / write speed in ubuntu server 8.04? no x windows

Hello,
I have a 16disk server with the disks setup in a raid 0. These run to a hardware raid controller with 512mb ram. I want to measure what the maximum megabytes per second read, and the maximum megabytes per second write. This server is a production database server running MYSQL. We are trying to gain performance insight to what we currently have compared to deploying a new server with nothing but SSD's.

Can anyone please tell me how to get the measurements I require?

Thanks,
Rick

The iostat utility comes to mind. It is part of the systat package and can be installed using the command "sudo apt-get install sysstat"
