The Backup Plus Portable 4TB USB 3.0 drive internally carries a Seagate/Samsung Momentus ST4000LM016 drive. Seagate recently launched the Backup Plus Portable 4TB USB 3.0 drive based on one of the first 4TB 2.5" drives in the market. 2TB USB 3.0 drives have been around for some time now, but the 4TB mark in the portable 2.5" form factor had only been achieved with dual drives and external power. From the perspective of that market, bus-powered external hard drives (2.5") are hard to beat. Unfortunately, the cost per GB is still too high for the average consumer. They have slowly been increasing in capacity too, and we even had a 1TB portable SSD from Samsung earlier this year. Flash drives and external SSDs can take advantage of the high-speed nature of the interface. The rise in popularity of USB 3.0 has enabled a large number of high-speed bus-powered storage devices.
