Solid-state drives (SSDs) are becoming increasingly popular in computers due to their superior performance. However, hard disk drives (HDDs) are still widely used due to their capacity to store large amounts of data inexpensively.
Meanwhile, Seagate’s latest HDDs offer both high speeds and large amounts of storage space at an affordable price. The company has announced the launch of the Mach.2 Exos 2X14, its first dual actuator hard drive and the fastest in the world. The Exos 2X14 hard disk has two actuators with read/write heads as opposed to traditional hard disks which have only one actuator. This doubles the read/write speed of the HDD.
Seagate has been working closely with Microsoft on this technology for many years, and its efforts have now paid off.
In addition to a total capacity of 14TB, this hard drive has a sustained transfer speed of 524MB/s, making it the fastest hard drive in the world right now. In essence, it is a combination of two 7TB hard drives combined in a helium-filled case. Its spindle speed is 7200 RPM, and it features a 256MB cache.
While testing the Exos 2X14 on a data centre server, the read and write speeds were comparable to some inexpensive SATA/SAS SSDs at a much lower cost. However, the new hard drive consumes slightly more power than the rest at 13.5W under heavy loads.
For now, only specific customers will be able to purchase the drive, and it will not be available to the general public anytime soon. Nevertheless, Seagate’s multi-actuator tech might show up on other HDDs.
