So im looking to get a cheap hard drive just to hold windows 7 and a few things everything else i can put on my 2tb external. So the question is will both of these work with the computer im trying to build because im completely new to this computer building thing, and if they both would work which ones better
Yes exactly, SATA has been the standard for almost a decade now. IDE drives are very, very old. Especially since you're building a solid computer (i5-3570K) you might not want to go too cheap on the hard drive, don't forget that your OS will be running on it so it will affect the performance. Look for Western Digital "Black" editions they have a good price/performance ratio.
