Samsung announces the “world’s first” 4TB USB-powered portable hard drives

Samsung – in partnership with Seagate – has announced the “world’s first 4TB USB-powered single drive solutions” that are housed in 2.5-inch enclosures. There are two models as a part of today’s news, the M3 and P3, coming in at 0.78 inches thin and weighing only 8.3 ounces. These will offer twice the capacity of Samsung’s 2TB portable drive while gaining 1/10-inch of thickness and can handle USB 3.0 speeds.

Both 4TB models will be available later this month directly from Samsung and other retailers. Pricing has yet to be announced at this time.

In need of some portable storage? Best Buy offers the Toshiba Canvio 1TB External USB 3.0 Hard Drive for $49.99. Amazon has Seagate’s Expansion 1TB for $54 as well. For those in need of larger capacities, check out this deal on a 8TB solution.


Samsung HDD Announces the Thinnest and Lightest Weight 4TB External Hard Drives in the World

June 17, 2015 08:01 AM Eastern Daylight Time

CUPERTINO, Calif.–(BUSINESS WIRE)–Samsung HDD, a division of Seagate Technology, today announced 4TB M3 Portable and the P3 Portable external hard drives, which are the first 4TB USB-powered single drive solutions to come in 2.5” cases in the world.

“The Spinpoint™ M10P 4TB hard drive enables this innovation with the highest aerial density, 800GB per disk in the world”

“Previously only attainable in desktop or bulky multi-drive internal designs, we can now achieve a 4TB capacity in a compact drive thanks to the latest Samsung HDD technology,” said Dave Klenske, director of product line management, Samsung HDD. “By going to a single drive solution, we can power the drive through just a USB connection while fitting it into a case that is only a 1/10 of an inch thicker than our 2TB drive. They are the perfect lightweight drives for notebook computer owners who need to access media collections too large to fit on traditional internal storage options.”

The 4TB Samsung® M3 Portable and the Samsung® P3 Portable drives measure 0.78 inches thin and weigh only 8.3 ounces and operate at USB 3.0 speeds without requiring any external power supplies.

“The Spinpoint™ M10P 4TB hard drive enables this innovation with the highest aerial density, 800GB per disk in the world,” said Doug DeHaan, general manager, Samsung HDD division. “With consumer demand for external storage capacity continuing to grow, the P3 and M3 4TB answer the increasing appetite for storage and are positioned to lead future capacity needs from the mobile market.”


The Samsung® 4TB M3 and MP Portable hard drives will be available in late June through authorized distributors. Learn more at
