Enable or disable NCQ for best performance?

[IT Troll]

I have just ordered one of these from overclockers:

Hitachi Deskstar T7K250 NCQ 250GB SATA-II 8MB Cache - OEM (0A31636)

But now I am confused about NCQ. Custom PC magazine says you must enable SATA-II and NCQ for best performance. But StorageReview shows it performing best (in most tests) without NCQ:

What is your advice?

Hmmm, both articles I mentioned were testing game loading times. Custom PC says to enable NCQ as it improves performance by 10%. But StorageReview show faster loading with NCQ turned off.

My system will have the O/S and games on the same drive (separate partitions).

Well Custom PCs advice was to enable it and that seems to be the consensus here (that would be my gut feeling too).

The issue is StorageReview show better performance with it disabled and they are fairly well respected aren't they?
