Seagate doubles HDD performance with multi-actuator technology
Seagate has taken the wraps off its Exos 2X14 enterprise hard drive. It's the first to integrate Seagate's MACH.2 multi-actuator technology, which is a method of turning one hard disk into two and doubling performance.
The technology is pretty straightforward. Say you have four platters in a disk drive. The actuator controls the drive heads and moves them all in unison over all four platters. Seagate's multi-actuator makes two independent actuators out of one, so in a six-platter drive, the two actuators cover three platters each.
