I'm currently RUNNING an 80 gig, 7200 RPM Seagate HDD through the IDE Parrallel plug. I'd like to up grade to a bigger main HDD and use the 80 gig as a backup and storage for little used files. Question- My motherboard supports IDE and SATA. Is it possible to run one HDD from the IDE plug and another from the SATA plug, or should both be run from the same type plugs. The reason is, I've heard SATA gives better performance.

Motherboard--eVGA nForce3 250 Chipset SATA Raid AGP8X
CPU--Athlon 64 2800 w/HTT 754 pin
RAM--1024MB-400MHz DDRI believe you can definitely do that.  But, if you want further confirmation, you might post here: http://www.evga.com/community/messageboard/forum.asp?FORUM_ID=26The SATA will give you quicker response times.
You can use the manuf. utilities that ship with the HDD to clone your system as is which is quicker than re-installing everything.
You will need to load the SATA DRIVERS first then do the clone.
On most machines the SATA then becomes the primary boot drive and you can then use your IDE drives for storage.
Check your MBoard DOCS as you can also usually change this boot priority if you have the need to have say a dual-boot setup...
