While modern laptops, phones, and other gadgets use solid-state drives for their fast read-write speeds, traditional hard-disk drives are still around. It’s mainly because HDDs are relatively cheap on a cost-per-gigabyte basis. Seagate, however, has unveiled its new MACH.2 HDD that not only provides a gargantuan 14TB capacity, but also a sustained transfer rate of 524MB/s.
At such rate, the Seagate MACH.2 Exos 2X14 holds the world record of fastest hard-disk drive. It’s so fast that it can keep up with the read-write speeds of some conventional SSDs. A normal HDD is only half as fast.

The HDD is able to achieve this feat by using a multi-actuator technology. Traditionally, HDDs only have one actuator or head arm that moves around the platters to read and write data. The fast transfer rate comes with a cost though—a high power consumption at 13.5W under heavy load.
The Seagate MACH.2 Exos 2X14 is only available to select customers, presumably enterprises.
