Seagate has just announced the Backup Plus 5TB portable hard disk drive. The new Seagate Backup Plus 5TB does not have any rival currently, as it’s the largest capacity mobile drive on the market.

If you’re wondering how big and heavy a 5TB portable hard-drive must be, the Seagate 5TB measures 11.5×7.8x2cm in dimensions – almost twice as thick as a Backup Plus Slim drive (1.2cm) – and weighs is less than a quarter of a kilogram, at 247g. That is been made possible by Seagate’s new technology behind its 5TB BarraCuda internal hard-drive, which was itself announced only last month.

That means you can use the 5TB Backup Plus Portable without an external power source, which is convenient especially if you are on the move. And there are not any data speed trade-offs, with new Seagate drive capable of 120MB/s over a USB 3.0 connection. The 5TB drive does not ship with a USB Type-C cable though, so you will need to use a dongle if you buy a laptop that only has USB Type-C ports.

Seagate reckons the new Backup Plus 5TB mobile drives offer the best of both worlds; desktop sized storage in a portable bus-powered form factor. You can connect these drives to your PC via USB 3.0 (45cm USB 3.0 cable included) but it is backwards compatible with the slower USB 2.0 standard. With a PC you can enjoy plug and play functionality while the Mac users can use NTFS for Mac driver software (included) to get the benefit of platform interchangeability.

It also sports an aluminum cover which helps to enhance the durability. As for pricing, the Seagate Backup Plus 5TB will retail for $190 and will be available for purchase later this month in the color options you see above.
