I am looking for a recommendation for an HDD to put into my uMBP 2009. I am planning on putting in an OWC SSD as my boot drive and I am looking for a 500GB 7200RPM drive for data. I have been considering either the Seagate 7200.4 or the WD Scorpio Black 500GB. Is there another drive that would be recommended? Also, does it matter what location I put either drive? Should I keep the HDD in the normal bay and the SSD in the optical bay or vice versa? Does it really matter? Lastly, can the LaCie Portable DVD USB drive be used to then install the OS onto the SSD once both drives are installed? I believe the answer is yes. Thanks!!
