Look out storage nuts, 3 terabytes is on the horizon. And it’s hot, literally. Anandtech reports that the 3 TB drive gets a little hot when put to work for extended periods. That what happens when you cram 5 platters into a 3.5″ plastic shell with little ventilation. Temperatures sometimes getting as hot as 69 degrees Celsius. Performance suffered as well. The heat issue could come back to bite you in the butt if you have any important data on the drive and happens to fail at a critical moment. However with this external unit available for sale the OEM 3 TB hard drive should be showing up at local retailers shortly.
I would take a pass on this one. Pickup two 1.5TB drives instead. USB 3.0 is nice but not worth the design risk. Also, who carries around 3 TB of data with them? There HAS to be a better way to transport data.
