Prev: NCQ vs TCQ performance?

Hi

In an article about the performance of sata raid controllers (
StorageReview:
http://www.storagereview.com/articles/200406/20040625TCQ_1.html?page=0%2C5
) using NCQ or TCQ. it stated that TCQ is much faster than NCQ:

"SATA TCQ and SATA RAID have the potential to deliver benefits to the
server market just as great as those of SCSI TCQ and SCSI RAID."

So by using a SATA-1 TCQ RAID controller and WD Raptor disks one can get
close to SCSI performance. (Sata 2 does not actually give the same
performance according other tests I have read.)

The article was written in 2004, and in four years much may have
happened with NCQ. So the question is, does anybody know if much has
happened with NCQ? or can I still trust the articles conclusions in
terms of its performance?

regards

tom
