Western Digital Caviar Blue 1TB 32MB Cache SATA Internal Hard Drive for $59.99 shipped with MClub membership. MClub is basically a subscription to Mwave’s discount and emailing list. Here is a screenshot for reference. It uses a high-density 2-platter design for better performance while reducing power usage. Note that it comes in OEM packaging, which means no pretty retail box but is otherwise identical. Most places have this SATA drive for over $75.
