Hypervolume throughput specifications

Hi all,

I'm looking for some specifications that I still wasn't able to find.
I know this will change depending on the type of physical disks and
their specifications, but is there some way to estimate the I/O
throughput an hypervolume can give ?

Suppose we say for a 72gb 10k RPM disk we can expect ~100 I/O per
second. If we create 9 8gb hypervolumes. Can we estimate the I/O
throughput for each of those hypers ?
Or for instance, can you estimate the I/O throughput for the whole
metavolume ? Suppose in this case it's a 64gb metavolume composed of
8gb hypers.

I'd really appreciate your help very much.
BTW, this will be all configured in Raid 0+1.

Tks
Diego
