How to enable Staggered Spinup for DIsk-utility Software raid?

I have a Mac Pro 3, 1 (early 2008) and was wondering if the system supports staggered spin-up. I have four 7200.12 Barracudas in the drive bays and use them for software strip volume via SoftRAID.
If the system does support staggered spin-up, how can I enable it. I was previous user of Bios operated hardware, (PC user is misleading :-p) so I am not familiar on how to enable those options on Macs.

Mac Pro 3,1, Macbook Pro 1,1,, Mac OS X (10.6.1)

I'm unaware of any such facility on the Mac Pro. It should be unnecessary.

Unless SoftRAID does something, but there ARE disk drives that by themselves will I am pretty sure, whether it also depends on the controller, not sure.

I know some external RAIDs used drives that did (Maxtor had) and sometimes a disk wasn't ready on time. And tweaking the driver or firmware for the controller can help.

On a PC you can add a delay in the BIOS to wait, yes.

The whole idea is so that you aren't requesting 4-5 drives pulling the amps/watts needed at once making it lighter load on PSU.

Is there a problem? have you asked the excellent, quick and helpfull SoftRAID support? or just "curiosity?"
