SATA vs. ATA

Also, which boards support NCQ, or is it purely in the drive?

no, both the Drive and Chipset have to support it.. believe the latest Intel chipset supports it, as well as the upcoming nForce 4 chipset

No difference? simply untrue.

I recieved my first sata drive today, its not a raptor because i needed something cheapish for my gigabytes, so i settled for the sata150 maxtor 7200 8mb cache.
Its a good drive and outperform's by almost double my pata maxtor drive under benchmark program (Both drives are same size -120gig)

you can't start your first post like this, lets see the numbers (make sure your ide channels are not in pio mode)...and also what you are using to bench these with. hdtach 3.x is a free benchmark program that is commonly used. also the entire drive model numbers too please.

And just how are Raptors the exception?
I'll tell you...they aren't.Raptors are exactly the same,just different speed. 10,000 RPM vs 7,200 RPM drives.It has nothing to do with SATA vs PATA

without doing a bunch of reseach i remeber that the new 2nd gen raptors were using some scsi type queuing or something to be a little better than the older ones in addition to just an increase in spindle speed.

The 2nd gen Raptor uses the very old ATA TCQ. It is not based on anything SCSI. It's a PATA drive bridged to SATA. Seagate's SATA drives are native SATA devices as are the the recently released Maxtor DM10 and Maxline III.

The only real world difference between SATA and PATA today is CPU utilization. While under extreme loads, SATA will exhibit a little more than half the utilization of PATA and come negligibly close to SCSI. In real world usage, the difference won't be that large, and you are very unlikely to notice any differences.
