Operating a RAID controller (Ultra ATA 133) with two HDs: one 133, the other 100

2

In this setup, will the RAID controller (I'm going to use the one integrated in the Gigabyte GA-7DXR+) run both disks in Ultra-ATA 100?

Or will it run the disks each with their native speeds (133/100) ? From my understanding of RAID, it should run the disks at their native speed.

I'm going to run it with RAID 1.

1With Raid it is always best to use matched hard drives, same model and firmware revision, not a must but would be wise. Intersecting question, one would assume Yes, I would contact Gigabyte support and ask them. – Moab – 2011-02-20T22:43:09.830

A raid1 will (almost) never run faster than the slowest disk. One exception is if your raid controller is smart enough to distribute read requests. The wikipedia has a good article about raid.
