Will TCQ function in RAID 0?

Hello All,

I have just received two shiny new WD 74GB Raptors, and I plan on running them in RAID 0.  I know these drives support TCQ (native command queing), but (hypothetically, since my current SATA controller does not) if my SATA controller did feature native command queing support, would this feature still function if this drives were set up in RAID 0?  Or will TCQ work with only a single drive?  Just curious.  Thanks!

You may have RAID0 performed by hardware (then the controller should be able to handle TCQ) or by software, like Windows (then again controller should be able to handle TCQ). It does´t matter.

As the SATA interface is point-to-point, one-to-one, there is no Master/Slave, no multiple adressing, I cannot see why TCQ wouldn´t work on any RAID configuration.

The SATA controller will allways "talk" and see individually any SATA disk, doesn´t matter if they are RAIDed or not.

Agree ?
