StorageReview.com has a new article which looks at the performance of new IDE/ATA hardware with TCQ (Tagged Command Queuing), which SCSI has had for years.
If you look at the performance figures, it looks like in most tests, RAID0 does next to nothing for single users (though it helps for servers), and that TCQ actually adds overhead that slows desktop systems down, though servers love it.
Overall, the fastest was the non-TCQ ATA RAID setup, followed by TCQ ATA RAID, with a SCSI array trailing behind by quite a distance. Interesting.
The results are completely different for multi-user server situations.
Any thoughts on this?
