I'm looking to purchase ASAP (i.e., before any more bills come due lol)
Approximate price range: ~$100
Preferred purchase site: www.newegg.com
I'm already running Win7 Ultimate 64-bit on a 90GB OCZ Sata-3 SSD, so this replacement hard drive would be for non-primary programs (for example: firefox, my document suite and a few very other items are already installed on the SSD), multimedia storage, games, and so forth.
I'm a bigger fan of Samsung Spinpoint F3 1TB drives but with the current pricing of HDDs, the Seagate is a good deal. Another note though, there is no real need for SATA-3 for a mechanical drive, so if you find a cheaper SATA-2, you would just as well off.
