So my finger is hovered over the buy now button on Newegg for the Seagate Momentus 500GB 7200RPM hard drive. I've read the reviews and criticisms but it seems like they might have fixed the problems with it over the last few months, (lets hope!). But, i see the Western Digital Scorpio 5400 RPM 500GB drive for sale for $99. I hear that its similar in performance. I need it for video editing to install in my 17" penryn MBP. Would i really otice a perceivable difference if i had the Western Digtal 5400RPM over the Seagate 7200RPM drive? As a possibly related piece of information; I called my local mac resaler who said that they don't even carry Seagate hard drives anymore! I asked why and the clerk didn't know. Is Segate going down the tubes? Are they a bad manufacturer? Any suggestions?
