Buy.com offers the Fantom Gforce/3 1TB USB 3.0 External Hard Drive model no. GF3B1000U32, for $89.99. This $20 mail-in rebate cuts it to $69.99. With free shipping, that's $0.07/GB and tied with our December mention of a similar drive as the least expensive 1TB USB 3.0 external hard drive we've seen. (It's also a current low for this specific model by $31.) It features a fan-free design for quiet operation. Rebate ends September 16.
