Double the capacity of current drives, and much more.
Seagate is one of the few hard drive manufacturers who focus on innovation, something that has been proven time and again since the past three decades when they launched the 5.25-inch 5 megabyte hard drive in 1980. In recent years their Momentus XT hybrid drive has been getting a lot of attention. Today Seagate has announced another new milestone in hard drive manufacturing: 1 terabit per square inch on their new hard drive platter.
Currently the highest hard drive in the market that comes in the 3.5-inch form factor goes up to 3TB, giving it 629 gigabits per square inch. Laptop drives in the 2.5-inch form factor top out at 500 gigabits per square inch with 750GB. Seagate achieved this 1 terabit per square inch landmark by Heat-assisted Magnetic Recording (HAMR), which is the next generation of the currently used Perpendicular Magnetic Recording (PMR).
Seagate expects to realize the benefits of HAMR technology by exceeding the 1 terabit per square inch capacity over the next decade, with hard drive sizes in the 3.5-inch format exceeding well over 60TB. In the near future, current high-end hard drives will be replaced with 6TB in 3.5-inch and 2TB in 2.5-inch form factor.
“The growth of social media, search engines, cloud computing, rich media and other data-hungry applications continues to stoke demand for ever greater storage capacity,” said Mark Re, senior vice president of Heads and Media Research and Development at Seagate. “Hard disk drive innovations like HAMR will be a key enabler of the development of even more data-intense applications in the future, extending the ways businesses and consumers worldwide use, manage and store digital content.”
