Madshrimps posted a review on the Hitachi Touro Desk Pro 4TB USB 3.0 External HDD

The refreshed Touro Desk Pro from Hitachi comes with a new high capacity 4TB drive, which succeeds to deliver better transfer speeds than the previous, 3TB model. The temperatures of the drives are close to the ones we have seen with the Touro Desk Pro 3TB and the enclosure has the same design lines.
