Any particular reason to avoid the Toshiba? I heard it's basically an HGST? At least, the HGST before WD's acquisition.
Here, the DT01ACA300 (3TB) is available for <95USD, and the cheapest 4TB drive (Hitachi 0S03362) costs 150USD.
P.S. The ST3000DM001 is available for <105USD, BTW. Both it and Toshiba has 2-year warranty only.
