If, for cost reasons, I try to mirror a slow disk with a fast disk,
is the S/W smart enough to balance the reads accordingly or will it
all slow down to the speed of the slowest?
For testing the raw disk thru put...
is there a character device for raw read/raw writes instead of
/dev/sdaxx that we can use to measure performance
on the raid drives??
is there a GUI based tool to use to watch the disk thru-put??
