I bought another $69.95
Amazon.com
Hitachi Deskstar 2 TB 3.5-Inch CoolSpin RPM SATA III 6Gbps 32 MB Cache Internal Hard Drive 0F12117 for my Mac Mini. But I ended up putting it on my Quad processor Ubuntu box.
Every time I buy one of these the price jumps back up ten dollars to support all the one Terabyte drives they haven't sold. But it keeps coming back down a few days later.
