MacMall offers the Fantom GreenDrive 1.5TB eSATA / FireWire 800 / USB 2.0 External Hard Drive, model no. GD1500Q, for $99.99 with free shipping ($0.07/GB). That's tied with our mention from last week and the least expensive 1.5TB FireWire 800 external hard drive we've seen. (It's also a current price low by $21.) This hard drive features an aluminum casing, fan-free design, 32MB cache, and up to 300MB/s transfer rate.
