benchmark a volume, not a physical drive?

Any tools out there to do this? I just re-attached my FC enclosure and setup a dynamic disk stripe across 6 drives. I've got single drive performance numbers, but HDTach and HD Tune both only benchmark physical drive performance. I want to benchmark the volume.

Any ideas?
 
Perhaps I show ignorance here, but both tools you mentioned show performance characteristics of RAID arrays, not just individual drives - or is that not what you mean?
 
I'm not even sure what you're asking...so apparently my ignorance is the English language :). Here's the setup I'd like to bench:

Fibre Channel drive enclosure direct attached to Emulex 4Gb/sec FC HBA
6x18GB Seagate FC 2Gb/sec drives in a Windows Vista Stripe
Volume has a drive letter, but no file system, yet (because file systems give you shit numbers, and I'm trying to compare the FC 6drive setup to my WD320AAKS 6drive SATA setup).

The tools I have allow me to bench the individual drives, but not the entire striped volume. I can bench the drives in the volume, individually, but this is not what I'm looking for.

They will do RAID arrays but only if it is created by a controller.
This RAID seems to have been made by the OS so the OS is actually seeing different physical drives and one volume, whereas when you use a controller based raid the computer only sees one physical drive and one volume.
