If you have just a single hard drive, there will not be much performance difference at all -- single drives can't push enough data to saturate either the IDE or SATA bus, and for the most part the drive mechanisms themselves are the same.
I'm not sure if switching to SATA connection would work -- Windows usually is not too pleased about having its device changed out from under it. You might have to do a repair or even reinstall to get it working properly...

So if I get a second drive and start out with that as a SATA cabled drive while the other one is attached via IDE does that make anything better or do you have to have 2 drives cabled as SATA before you see a difference?
The drive was installed using an IDE ribbon cable into an IDE socket rather than using a SATA cable into a SATA socket.
Both are available on the TYAN motherboard. The builder just took the easiest way out as far as I can see. He didn't supply any SATA cables either. I bought the cable thinking I might change it, hence the question in the Subject line.
Since everyone seems to think it wouldn't do much, I'm going to leave it as is.
My apologies I thought you said you had.
That Maxtor 7V250F0 drive does it have both SATA and PATA pins sockets? I thought only SATA 8 pins, if it as both then you could Raid on IDE or SATA if you got another drive the same make and capacity.
