Have a look at this site. Tells you how to install a new PS3 Hard Disk Drive. To my knowledge, you need a 2.5" SATA HDD, @ 5400RPM or 7200RPM. So it looks like that Hard Drive would work. But I wouldn't buy from eBay, use http://newegg.com if you live in USA.

(A list of 320GB Hard Drive's from Newegg - You take your pick. As long as they are a 2.5" SATA Hard Drive with 5400RPM or 7200RPM it's fine).
