Question about SATA vs SCSI

I just purchased a new ASUS P5AD2-E Premium motherboard and I'm about to connect my hardrives.

I have a new Maxtor Diamondmax 10 160GB SATA 7200 RPM drive and a Quantum U160 SCSI 10k RPM drive.

Which should I go with? I'm assuming the SCSI will be faster, but will it be much faster? Since, using SCSI will take some work off the CPU...is it worth it? will I notice much performance difference?

 

If you already have the drives then why not simply put them both in? SATA and SCSI are separate things, you don't have to use one or the other. That is of course considering the motherboard has SATA and SCSI avaliable.

 

I'm building a second computer. One drive is going in one, while the other drive will be in the other.

 

my 15,000 rpm scsi performs mucho faster then the sata 10,000
intel 845 perl board,
2.8 ghz, 1 gig ram.
go with scsi, one can move a scsi with xp from computer to computer without
any problems
