Trans Intl. offers the ProStor 1TB Portable eSATA / FireWire 800 / USB 2.0 External Hard Drive for $158 plus $8 for shipping ($0.17/GB). That ties our mention from last week as the lowest total price we could find for this drive. This 1TB external hard drive features an aluminum casing, 8MB cache, eSATA and USB combo port, FireWire 800 port, and FireWire 400 port.
