HDD Command queue

I know this still might be a bit early but those few that have a mobo/controller card and HDD that support command queues

How is the performance gain when multitasking, any noticiable improvements?

Is it stable yet or still causing data corruption?

Thinking about making a PC again since programing and working in C# on a mac has been a little frustrating. Been out of touch lately and did a search and did not find much discussion concerning this fact.

all HDDs have one form of command queing or another (well maybe not antiques)

As the Hard Disc Spins VI: Command Queuing

but I assume your talking about SATA Native Command Queing?
the drives and chipsets that support it do quite a nice job of it
I dont happen to have one or the other though
